§5 The Ethics of Belief and Implicit Bias

As we conclude our look at the obstacles to critical thinking, we must move from simply identifying errors to establishing an ethical framework for our mental lives. Critical thinking is not just a cognitive skill; it is a moral responsibility.

5.1 Evidentialism and the Clifford Standard

The philosophical foundation of this course is Evidentialism, famously championed by W. K. Clifford. He argued that how we handle evidence is a matter of public safety and personal integrity.

• The Philosophical Prescript: It is “wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.”

• Proportioning Belief: This stance requires us to proportion the strength of our belief to the strength of our reasons. If the evidence is weak, our conviction should be equally weak.

5.2 Implicit Bias: The Hidden Obstacles

Many obstacles to critical thinking are unconscious. Research into Implicit Bias shows that we hold stereotypes and prejudices that influence our judgment without our awareness. Unlike the “self-interested thinking” discussed in Section 2, these biases can conflict with our stated, conscious values.

Evidence in the Real World:

• In Hiring: In a well-known study on racial cognition, researchers sent out nearly 5,000 resumes in response to help-wanted ads. Resumes with “White-sounding” names received 50% more callbacks for interviews than identical resumes with “Black-sounding” names (roughly 1 callback for every 10 resumes vs. 1 for every 15).

• In Sports: A study of NBA officiating found that white referees called fouls at a 4.5% higher rate against Black players than against white players, while Black referees called fouls at a slightly higher rate against white players.

5.3 Stereotype Threat

A related phenomenon is Stereotype Threat. This occurs when individuals underperform because they are aware of a negative stereotype about their group, leading to increased self-doubt and anxiety.

• Women in Philosophy: Jennifer Saul notes that while women’s underrepresentation in philosophy is often blamed on “innate nature” or “socialization,” it is more likely driven by implicit bias and stereotype threat. When women are reminded of the stereotype that “philosophy is for men,” their performance on logical and philosophical tasks can decrease, creating a cycle of underperformance and exclusion.
