All questions

Question 1

A medical device company is using a scoring model to screen new product ideas. An idea for a novel diagnostic tool receives a very high score for 'market potential' and 'strategic fit' but a very low score for 'technical feasibility' due to reliance on a technology that is still in theoretical stages. What is the most prudent next step for the product manager to take?

  1. Immediately discard the idea, as the technical risk is too high to justify further investment.
  2. Proceed directly to concept testing with potential customers, since high market potential is the most important factor.
  3. Table the idea but commission a long-term R&D project to explore the required technology for future consideration. (correct answer)
  4. Advance the idea to the business analysis stage to quantify the potential profit, which could justify the technical challenges.
Explanation: The core function of idea screening is to filter ideas, not just accept or reject them wholesale. An idea with high potential but significant technical hurdles shouldn't be discarded immediately, nor should it proceed as if the hurdle doesn't exist. The most strategic action is to recognize the long-term potential while addressing the technical gap separately through focused R&D, effectively putting the product idea on hold until the technology matures. Proceeding to concept testing (B) or business analysis (D) would be premature and waste resources on a product that cannot yet be built.

Question 2

A consumer electronics firm launched an innovative, AI-powered personal assistant device. Pre-launch concept tests showed high purchase intent. However, post-launch sales were extremely low. Customer feedback revealed that while the device's advertised capabilities were impressive, the setup process was confusing and it failed to reliably connect with other smart devices in their homes. This failure is most directly attributable to a breakdown in which NPD stage?

  1. Marketing Strategy Development
  2. Business Analysis
  3. Product Development (correct answer)
  4. Idea Screening
Explanation: The core problem identified is poor usability, a confusing setup, and unreliable performance. These issues relate directly to the physical design, engineering, and functionality of the product itself. The Product Development stage is where the concept is turned into a physical, working product. A failure in this stage results in a product that doesn't perform as intended or provides a poor user experience, even if the idea and marketing strategy are sound. The idea passed screening (D), and while the business analysis (B) was ultimately wrong, the root cause was the faulty product, not the financial model.

Question 3

A snack company wants to quickly gauge consumer response to a new flavor of tortilla chip and test two different advertising campaigns. They recruit shoppers at a local mall, show them one of the two ads, and then give them a voucher to pick a snack from a simulated store shelf containing the new product and several competing brands. This method of market testing is best described as a:

  1. Standard test market.
  2. Controlled test market.
  3. Simulated test market. (correct answer)
  4. Concept use test.
Explanation: This is a classic description of a simulated test market (STM). It creates an artificial or simulated shopping environment to expose consumers to a new product and marketing stimuli. It is not a standard test market (A), which uses real stores in a real city. It is not a controlled test market (B), which involves a panel of stores that have agreed to carry new products for a fee. It is not a concept use test (D), which typically involves giving consumers the product to use at home and report on their experience, without the shopping context.

Question 4

During the product development stage for a new kitchen blender, the engineering team creates the first working prototype. From a marketing perspective, what is the most important use of this initial prototype?

  1. To provide to the legal team for patent application illustrations.
  2. To enable consumer use testing to gather feedback on ergonomics, functionality, and performance. (correct answer)
  3. To create realistic product images for the commercialization launch campaign.
  4. To calculate the final bill of materials for accurate cost projections.
Explanation: While a prototype serves many functions (A, C, D), its most critical role from a marketing and product development standpoint is to facilitate learning. It allows the company to move from a theoretical concept to a tangible object that can be tested with real users. This consumer use testing provides invaluable feedback on what works and what doesn't, allowing for refinement before committing to expensive production tooling. The other uses are secondary to this primary function of validation and iteration.

Question 5

A firm develops a breakthrough technology for water purification. The R&D department creates a highly effective, but complex and expensive, home purification unit. The firm positions it as a premium product for health-conscious consumers. The product fails. A competitor later uses the same core technology to create inexpensive, portable water bottles with built-in filters, which are a huge success. The first firm's failure is best described as:

  1. A technology-driven product launch that failed to identify the correct market application. (correct answer)
  2. A failure in the business analysis stage, overestimating the size of the premium market.
  3. A marketing strategy that was underfunded and unable to educate consumers.
  4. A product development process that resulted in a low-quality, unreliable product.
Explanation: This is a common pitfall where a company falls in love with its technology and builds the most advanced product possible, rather than starting with a customer problem and finding the best application for the technology. This is a 'technology push' approach. The first firm had a solution (the technology) and built a product around it, without properly identifying the market's preferred application (portability and affordability). The competitor succeeded with a 'market pull' approach, applying the technology to solve a more widespread consumer need. While the business analysis was likely wrong (B), the root cause was the flawed application of the technology.

Question 6

A large CPG company has completed a successful regional test market for a new laundry detergent and is preparing for commercialization. The team's most pressing decisions at this stage will primarily involve:

  1. Allocating the production ramp-up budget and developing the national launch timetable. (correct answer)
  2. Conducting a detailed business analysis to re-confirm profitability forecasts.
  3. Finalizing the brand name and packaging design based on consumer feedback.
  4. Screening new ideas for potential line extensions of the detergent.
Explanation: This question tests your understanding of the new product development (NPD) process, specifically the commercialization stage. When you see questions about post-test market decisions, focus on what activities are most critical and time-sensitive for a successful product launch. At the commercialization stage, the product concept, design, and market viability have already been validated through testing. The most pressing decisions now center on execution - specifically production scaling and launch timing. Answer A correctly identifies these priorities: allocating production ramp-up budgets ensures sufficient inventory to meet anticipated demand, while developing a national launch timetable coordinates all market entry activities across regions. Answer B is incorrect because detailed business analysis and profitability forecasting should have been completed before the test market, not after a successful one. This represents a fundamental misunderstanding of the NPD sequence. Answer C is wrong because brand name and packaging design must be finalized before test marketing - you can't test a product without these elements already in place. Companies don't wait until commercialization to make these core decisions. Answer D incorrectly focuses on future line extensions rather than the immediate task of launching the current product successfully. While line extension ideas may emerge, they're not the most pressing commercialization decisions. Study tip: Remember that each NPD stage has distinct priorities. When answering commercialization questions, think "execution and scaling" rather than "development and testing." The key shift is from validating the product concept to successfully bringing it to market at scale.

Question 7

A startup is racing to launch its new mobile app before a major competitor. The CEO decides to skip the planned beta testing phase (a form of test marketing) and proceed directly to a full public launch on the app store. What is the most significant strategic risk associated with this decision?

  1. Early adopters might give the app negative reviews due to undiscovered bugs, crippling its long-term potential. (correct answer)
  2. The final development costs may be higher than originally budgeted.
  3. The company will be unable to generate pre-launch press coverage and buzz.
  4. The marketing team will not have a finalized product to use in its advertising creative.
Explanation: When you encounter questions about skipping test marketing phases, focus on the core purpose of testing: identifying and fixing problems before they reach your entire target market. Test marketing, including beta testing, serves as a critical risk mitigation strategy that can make or break a product launch. The most significant risk of bypassing beta testing is that early adopters might give the app negative reviews due to undiscovered bugs, crippling its long-term potential (A). This creates a devastating cascade effect: poor initial reviews damage the app's ranking in app stores, reduce download rates, and create negative word-of-mouth that's extremely difficult to overcome. In mobile apps especially, first impressions are often permanent impressions since users quickly delete problematic apps and rarely return. Option B is incorrect because development costs are largely sunk by launch time - skipping beta testing actually reduces immediate costs, though it may increase post-launch fix expenses. Option C misunderstands beta testing's role; beta testing typically generates limited press coverage since it involves small, controlled user groups rather than major publicity campaigns. Option D incorrectly assumes the marketing team needs a completely bug-free product for advertising - marketing materials are usually created around core features and benefits, not technical perfection. Remember this key principle: in digital products, negative reviews compound rapidly and are nearly impossible to reverse. Questions about rushing to market often test whether you understand that short-term competitive advantages rarely outweigh the long-term damage from launching flawed products to your entire customer base.

Question 8

A B2B company that produces advanced materials for manufacturing wants to generate ideas for new product applications. To gain the deepest insights into the latent needs and unarticulated problems of its industrial customers, which idea generation technique would be most effective?

  1. Distributing a survey to its sales force to gather their ideas and recent customer requests.
  2. Conducting on-site observational research, where engineers spend time at customer facilities watching their production processes. (correct answer)
  3. Analyzing competitors' product catalogs and recent patent filings to identify gaps in the market.
  4. Hosting an internal innovation tournament where employees from all departments submit and vote on new product ideas.
Explanation: For uncovering latent, unarticulated needs, direct observation (a form of ethnographic research) is most effective. Customers often cannot articulate their problems or the solutions they need. By observing them in their own environment, the company's engineers can spot inefficiencies, workarounds, and challenges that the customers themselves may take for granted. The other methods are valuable but less likely to yield such deep insights. Sales force surveys (A) are filtered by sales priorities, competitor analysis (C) is reactive, and internal tournaments (D) lack direct customer context.

Question 9

During the product development stage for a new kitchen blender, the engineering team creates the first working prototype. From a marketing perspective, what is the most important use of this initial prototype?

  1. To provide to the legal team for patent application illustrations.
  2. To enable consumer use testing to gather feedback on ergonomics, functionality, and performance. (correct answer)
  3. To create realistic product images for the commercialization launch campaign.
  4. To calculate the final bill of materials for accurate cost projections.
Explanation: While a prototype serves many functions (A, C, D), its most critical role from a marketing and product development standpoint is to facilitate learning. It allows the company to move from a theoretical concept to a tangible object that can be tested with real users. This consumer use testing provides invaluable feedback on what works and what doesn't, allowing for refinement before committing to expensive production tooling. The other uses are secondary to this primary function of validation and iteration.

Question 10

A snack food company is considering launching a new line of spicy potato chips. Management is debating whether to conduct a standard test market. Which of the following factors would most strongly argue against conducting a standard test market?

  1. The capital investment required for full-scale production is exceptionally high.
  2. A major competitor is known for its ability to rapidly reverse-engineer and launch imitative 'me-too' products. (correct answer)
  3. The company is uncertain about the most effective advertising message to drive trial.
  4. The product's recipe is complex and the company is concerned about maintaining quality in mass production.
Explanation: A standard test market involves launching a product in a limited number of representative cities, which makes the product and its marketing strategy visible to competitors. If a competitor can quickly imitate the product, the test market essentially provides them with a free look at the company's plans, erasing the first-mover advantage. High investment (A), uncertainty about advertising (C), and production concerns (D) are all strong reasons in favor of conducting a test market to mitigate risk before a full launch.

Question 11

A company launched a new line of eco-friendly cleaning products priced 40% above market leaders. The marketing highlighted its plant-based ingredients. The product failed to achieve its sales targets. Post-launch research revealed that while consumers supported the eco-friendly concept, they did not believe the product cleaned any more effectively than existing, cheaper 'green' options. This failure is primarily due to a flaw in:

  1. The product's value proposition and differentiation. (correct answer)
  2. The marketing communications budget.
  3. The product's distribution channels.
  4. The business analysis and sales forecasting.
Explanation: This question tests your understanding of value proposition - the unique combination of benefits a product offers that justifies its price point and distinguishes it from competitors. The scenario reveals a critical marketing failure: the company positioned its eco-friendly cleaning products at a 40% premium but failed to communicate a compelling reason why consumers should pay more. While the products were plant-based, consumers didn't perceive them as more effective than existing cheaper green alternatives. This means the value proposition was weak - consumers couldn't see enough differentiated value to justify the higher price. Answer A is correct because the core problem lies in value proposition and differentiation. The company didn't establish a clear, compelling reason why their product was worth 40% more than competitors. Simply being "eco-friendly" wasn't sufficient differentiation when cheaper green options already existed. Answer B is wrong because increasing the communications budget wouldn't fix the fundamental problem - consumers understood the eco-friendly message but didn't find it compelling enough to justify the premium price. Answer C is incorrect because there's no indication that distribution was the issue. The problem was consumer perception of value, not product availability. Answer D misses the mark because this wasn't about forecasting accuracy. The company may have correctly projected demand for a well-differentiated eco-friendly product, but they failed to actually create that differentiation. Remember: When you see premium pricing failures, look first at value proposition. Consumers will pay more only when they perceive significantly greater value - whether through superior performance, unique benefits, or meaningful differentiation.

Question 12

A product manager is using the 'Real, Win, Worth it' (R-W-W) framework to evaluate a new software idea. The analysis shows: the technology is feasible and the market is large ('Real'); the financial projections show strong potential ROI ('Worth it'). However, the analysis also shows the market has two dominant, well-funded competitors with high brand loyalty. Which question within the R-W-W framework does this competitive landscape most directly challenge?

  1. Is there a real need in the market?
  2. Can our company make the product?
  3. Will the product be profitable?
  4. Can the product be competitive? (correct answer)
Explanation: The Real, Win, Worth it (R-W-W) framework helps product managers systematically evaluate new product opportunities by asking three critical questions: Is it Real? (market need and technical feasibility), Can we Win? (competitive advantage), and Is it Worth it? (financial viability). Each pillar must be solid for a product to succeed. In this scenario, you need to map the competitive challenge to the correct R-W-W pillar. The presence of two dominant, well-funded competitors with high brand loyalty directly threatens the company's ability to gain market share and establish a competitive position. This competitive landscape makes it difficult for the new entrant to "Win" in the marketplace, regardless of market size or technical feasibility. Answer D correctly identifies that competitive positioning falls under the "Can we Win?" question of the R-W-W framework. When established competitors have strong brand loyalty and deep pockets, new entrants face significant barriers to gaining market traction. Answer A is wrong because market need has already been established—the analysis confirms the market is large and real. Answer B is incorrect because technical feasibility was confirmed in the "Real" assessment. Answer C misses the mark because while profitability projections look strong on paper, the competitive reality threatens the ability to achieve those projections. Remember that the R-W-W framework requires all three elements to align. Even when market opportunity ("Real") and financial potential ("Worth it") look promising, competitive dynamics in the "Win" category can kill an otherwise attractive product opportunity. Always assess competitive positioning as a separate, critical factor.

Question 13

In a concept test for a new online fitness subscription, 90% of respondents indicated a 'high likelihood' of purchasing. The company launched the service with an expensive marketing campaign, but subscriber numbers were less than 10% of the forecast. What is the most likely reason for this discrepancy?

  1. The marketing campaign used the wrong media channels to reach the target audience.
  2. Competitors launched similar services between the time of the test and the product launch.
  3. The sample of respondents in the concept test was not representative of the target market.
  4. The concept test suffered from a social desirability bias, leading to an inflated measure of purchase intent. (correct answer)
Explanation: When you encounter questions about concept testing and purchase intent, the key issue is understanding how consumer research responses often differ from actual buying behavior. This disconnect is one of the most common challenges in marketing research. The correct answer is D because social desirability bias occurs when respondents give answers they think are "socially acceptable" or that make them look good, rather than their true feelings. In concept tests, people often overstate their purchase intent because saying "yes, I'd buy that" feels like the "right" answer, especially for products with positive associations like fitness. A 90% purchase intent followed by such dramatically low actual sales is a classic sign of this bias inflating the results. Option A is incorrect because if the wrong media channels were used, you'd expect some subscriber uptake from other sources or word-of-mouth, not the massive gap described. Option B doesn't explain the severity of the discrepancy – competitive launches might reduce sales but wouldn't typically cause a 90% shortfall from projections. Option C suggests sampling issues, but even with some sample problems, a representative portion of respondents would likely convert, making the 90% gap unlikely. The key study tip: When you see extreme discrepancies between stated intent and actual behavior (especially 80%+ gaps), immediately consider social desirability bias. This is particularly common with "aspirational" products like fitness, health, education, or environmentally-friendly items where consumers want to appear virtuous but may not follow through with purchases.

Question 14

During the 18-month development cycle for a new piece of project management software, the product manager approved numerous feature requests from the sales, marketing, and executive teams. The final product was feature-rich but delayed, over budget, and so complex that the core target market of small businesses found it unusable. This product failure is a direct result of a breakdown in which aspect of the development process?

  1. Idea generation
  2. Competitive analysis
  3. Marketing communications strategy
  4. Scope management and control (correct answer)
Explanation: When evaluating product development failures, focus on identifying which stage of the process broke down based on the specific symptoms described. This scenario presents classic signs of poor project control rather than strategic or creative issues. The correct answer is D because scope management and control is the systematic process of defining what features will be included in a product and preventing uncontrolled changes during development. In this case, the product manager continuously approved new feature requests from various stakeholders without considering the impact on timeline, budget, or user experience. This "scope creep" led directly to the three major problems: delays (timeline exceeded), cost overruns (budget exceeded), and user confusion (complexity exceeded target market needs). Effective scope management would have involved evaluating each request against the original product vision and target market requirements. Option A is incorrect because idea generation refers to the initial brainstorming phase where product concepts are created. The core software idea appears sound—the failure occurred during execution, not conception. Option B is wrong because competitive analysis involves studying rival products to inform positioning and features. While better competitive research might have helped, the primary issue was uncontrolled feature additions, not lack of market intelligence. Option C is incorrect because marketing communications strategy deals with how you'll promote and message the product to customers. The product failed before it even reached the communication stage due to usability issues. Remember: When you see development problems involving timeline delays, budget overruns, and feature bloat, think scope management first—it's often the root cause of execution failures.

Question 15

A medical device company is using a scoring model to screen new product ideas. An idea for a novel diagnostic tool receives a very high score for 'market potential' and 'strategic fit' but a very low score for 'technical feasibility' due to reliance on a technology that is still in theoretical stages. What is the most prudent next step for the product manager to take?

  1. Immediately discard the idea, as the technical risk is too high to justify further investment.
  2. Proceed directly to concept testing with potential customers, since high market potential is the most important factor.
  3. Table the idea but commission a long-term R&D project to explore the required technology for future consideration. (correct answer)
  4. Advance the idea to the business analysis stage to quantify the potential profit, which could justify the technical challenges.
Explanation: The core function of idea screening is to filter ideas, not just accept or reject them wholesale. An idea with high potential but significant technical hurdles shouldn't be discarded immediately, nor should it proceed as if the hurdle doesn't exist. The most strategic action is to recognize the long-term potential while addressing the technical gap separately through focused R&D, effectively putting the product idea on hold until the technology matures. Proceeding to concept testing (B) or business analysis (D) would be premature and waste resources on a product that cannot yet be built.

Question 16

A consumer electronics firm launched an innovative, AI-powered personal assistant device. Pre-launch concept tests showed high purchase intent. However, post-launch sales were extremely low. Customer feedback revealed that while the device's advertised capabilities were impressive, the setup process was confusing and it failed to reliably connect with other smart devices in their homes. This failure is most directly attributable to a breakdown in which NPD stage?

  1. Marketing Strategy Development
  2. Business Analysis
  3. Product Development (correct answer)
  4. Idea Screening
Explanation: The core problem identified is poor usability, a confusing setup, and unreliable performance. These issues relate directly to the physical design, engineering, and functionality of the product itself. The Product Development stage is where the concept is turned into a physical, working product. A failure in this stage results in a product that doesn't perform as intended or provides a poor user experience, even if the idea and marketing strategy are sound. The idea passed screening (D), and while the business analysis (B) was ultimately wrong, the root cause was the faulty product, not the financial model.

Question 17

A company launched a premium, organic baby food line. The product had superior ingredients and was well-designed. However, it failed because it was sold in large, glass jars, which busy parents found inconvenient and unsafe compared to the lightweight, resealable pouches offered by competitors. In this case, the product failure was primarily caused by a misjudgment of:

  1. The core product benefit.
  2. The augmented product attributes.
  3. The actual product attributes. (correct answer)
  4. The product's positioning strategy.
Explanation: This question requires applying the three levels of product concept. The core benefit (nutrition for babies) was likely met. The augmented product includes things like warranty or customer service, which were not the issue. The failure occurred at the actual product level, which includes features, design, quality, and packaging. The inconvenient and unsafe glass jar packaging is a critical attribute of the actual product that was misaligned with consumer needs, leading to failure despite a good core product.

Question 18

A product manager is using the 'Real, Win, Worth it' (R-W-W) framework to evaluate a new software idea. The analysis shows: the technology is feasible and the market is large ('Real'); the financial projections show strong potential ROI ('Worth it'). However, the analysis also shows the market has two dominant, well-funded competitors with high brand loyalty. Which question within the R-W-W framework does this competitive landscape most directly challenge?

  1. Is there a real need in the market?
  2. Can our company make the product?
  3. Will the product be profitable?
  4. Can the product be competitive? (correct answer)
Explanation: The Real, Win, Worth it (R-W-W) framework helps product managers systematically evaluate new product opportunities by asking three critical questions: Is it Real? (market need and technical feasibility), Can we Win? (competitive advantage), and Is it Worth it? (financial viability). Each pillar must be solid for a product to succeed. In this scenario, you need to map the competitive challenge to the correct R-W-W pillar. The presence of two dominant, well-funded competitors with high brand loyalty directly threatens the company's ability to gain market share and establish a competitive position. This competitive landscape makes it difficult for the new entrant to "Win" in the marketplace, regardless of market size or technical feasibility. Answer D correctly identifies that competitive positioning falls under the "Can we Win?" question of the R-W-W framework. When established competitors have strong brand loyalty and deep pockets, new entrants face significant barriers to gaining market traction. Answer A is wrong because market need has already been established—the analysis confirms the market is large and real. Answer B is incorrect because technical feasibility was confirmed in the "Real" assessment. Answer C misses the mark because while profitability projections look strong on paper, the competitive reality threatens the ability to achieve those projections. Remember that the R-W-W framework requires all three elements to align. Even when market opportunity ("Real") and financial potential ("Worth it") look promising, competitive dynamics in the "Win" category can kill an otherwise attractive product opportunity. Always assess competitive positioning as a separate, critical factor.

Question 19

A large CPG company has completed a successful regional test market for a new laundry detergent and is preparing for commercialization. The team's most pressing decisions at this stage will primarily involve:

  1. Allocating the production ramp-up budget and developing the national launch timetable. (correct answer)
  2. Conducting a detailed business analysis to re-confirm profitability forecasts.
  3. Finalizing the brand name and packaging design based on consumer feedback.
  4. Screening new ideas for potential line extensions of the detergent.
Explanation: This question tests your understanding of the new product development (NPD) process, specifically the commercialization stage. When you see questions about post-test market decisions, focus on what activities are most critical and time-sensitive for a successful product launch. At the commercialization stage, the product concept, design, and market viability have already been validated through testing. The most pressing decisions now center on execution - specifically production scaling and launch timing. Answer A correctly identifies these priorities: allocating production ramp-up budgets ensures sufficient inventory to meet anticipated demand, while developing a national launch timetable coordinates all market entry activities across regions. Answer B is incorrect because detailed business analysis and profitability forecasting should have been completed before the test market, not after a successful one. This represents a fundamental misunderstanding of the NPD sequence. Answer C is wrong because brand name and packaging design must be finalized before test marketing - you can't test a product without these elements already in place. Companies don't wait until commercialization to make these core decisions. Answer D incorrectly focuses on future line extensions rather than the immediate task of launching the current product successfully. While line extension ideas may emerge, they're not the most pressing commercialization decisions. Study tip: Remember that each NPD stage has distinct priorities. When answering commercialization questions, think "execution and scaling" rather than "development and testing." The key shift is from validating the product concept to successfully bringing it to market at scale.

Question 20

In a concept test for a new online fitness subscription, 90% of respondents indicated a 'high likelihood' of purchasing. The company launched the service with an expensive marketing campaign, but subscriber numbers were less than 10% of the forecast. What is the most likely reason for this discrepancy?

  1. The marketing campaign used the wrong media channels to reach the target audience.
  2. Competitors launched similar services between the time of the test and the product launch.
  3. The sample of respondents in the concept test was not representative of the target market.
  4. The concept test suffered from a social desirability bias, leading to an inflated measure of purchase intent. (correct answer)
Explanation: When you encounter questions about concept testing and purchase intent, the key issue is understanding how consumer research responses often differ from actual buying behavior. This disconnect is one of the most common challenges in marketing research. The correct answer is D because social desirability bias occurs when respondents give answers they think are "socially acceptable" or that make them look good, rather than their true feelings. In concept tests, people often overstate their purchase intent because saying "yes, I'd buy that" feels like the "right" answer, especially for products with positive associations like fitness. A 90% purchase intent followed by such dramatically low actual sales is a classic sign of this bias inflating the results. Option A is incorrect because if the wrong media channels were used, you'd expect some subscriber uptake from other sources or word-of-mouth, not the massive gap described. Option B doesn't explain the severity of the discrepancy – competitive launches might reduce sales but wouldn't typically cause a 90% shortfall from projections. Option C suggests sampling issues, but even with some sample problems, a representative portion of respondents would likely convert, making the 90% gap unlikely. The key study tip: When you see extreme discrepancies between stated intent and actual behavior (especially 80%+ gaps), immediately consider social desirability bias.
