Based on lessons in this module (2), drag/drop the scenario/example to the type of bias it best represents. Confirmation bias, Status Quo bias, Halo effect, and Horns effect.
Confirmation: A member of a project team believes the team is using an inefficient methodology to execute and manage the project. To prove this point, the team member seeks out and summarizes information that verifies the flaws associated with the chosen methodology and ignores any evidence to the contrary. The team member presents this information to the project manager's supervisor as justification to change the team's methodology. Status Quo: An organization is recruiting a new CIO (Chief Information Officer) and is considering three candidates. All candidates have exceptional qualifications and leave positive first impressions on the organizational employees they meet during the interview process. In a late stage of the interview process, Candidate A proposes the adoption of a cloud-based enterprise system that would help the organization streamline their processes and better leverage organizational data for decision making, while Candidates B and C propose working within the practices that are already in place. Several employees do not wish to learn how to use a new system and change the way they do their jobs, even if doing so would improve organizational outcomes, so they express strong disapproval of Candidate A in favor of Candidates B and C. Halo Effect: Three candidates are being considered to fill one spot on a management team that will lead a major organizational project. The team's project lead does not personally know all three candidates but observes that one candidate stands out as being the most physically attractive. Despite this candidate having the most inferior credentials of the three candidates, the hiring manager feels most inclined to recruit this candidate to the management team. Horns Effect: A recruiter interviews a candidate who appears reserved and shy. Based on this first impression, the recruiter assumes the candidate will be incapable of effectively communicating with clients and connecting with other employees. Despite the candidate having letters of recommendation that highlight the candidate's effective communication and teamwork skills, the recruiter continues to believe the candidate lacks skills in these areas.
