We often evaluate things without examining what influences our decisions. A hypothetical scenario of a substitute teacher grading students from various socioeconomic backgrounds suggests that socioeconomic class can influence evaluations, even if unintentionally. This sets the stage for understanding bias in decision-making.
A 1983 study by Princeton psychologist Darlene Gross, involving a fourth-grade girl named Hannah, demonstrated confirmation bias. Participants were told Hannah was either rich or poor, then watched the same video of her performing tasks. Their evaluations of her academic ability were significantly influenced by their preconceived notions of her socioeconomic status. This illustrates how people interpret ambiguous information to confirm prior beliefs. Confirmation bias affects various professions and individuals, regardless of self-interest.
Beyond confirmation bias, other heuristics and biases influence our decisions without our awareness. Examples include affinity bias (liking/disliking influencing judgment) and in-group favoritism (favoring those in our own groups). Research consistently shows that everyone, regardless of expertise, is susceptible to automatic cognitive processes that skew decision-making. Our brains use schemas and shortcuts to navigate the complex world, which, while generally beneficial, also make us prone to biases.
The concept of equity, defined as a commitment to a fair 'tournament of merit,' implies equal scores for equal performance and equal investment for equal talent. However, implementing this is difficult due to biases. Our biases often disproportionately and systemically benefit some groups while harming others, often unconsciously through implicit stereotypes and attitudes we don't realize we possess. These implicit biases, demonstrated by decades of research, can lead to discrimination based on categories like race, gender, and age, threatening true meritocracy.
Despite the pervasive nature of implicit bias, we are not immune to it and can take steps to counter its effects. The video concludes by inviting viewers to watch the next installment, "Implicit Bias Lesson 1: Schemas," to learn more about addressing these biases.
