Why You’re Not as Rational as You Think: The Cognitive Biases That Rule Your Mind
Explore the scientific evidence behind the mental shortcuts and biases that undermine your rationality every day.
Rationality is often touted as the hallmark of human intelligence. Yet, decades of psychological research reveal that our minds are riddled with biases and shortcuts that systematically distort our thinking. This blog uncovers some of the most fascinating cognitive biases and their implications.
Narrative Bias: Memory as a Fluid Story
Your memories are not factual recordings but stories your brain reconstructs, influenced by current beliefs. This fluidity means your sense of self is a story that evolves, sometimes stubbornly resisting contradictory facts.
The Common Belief Fallacy and Scientific Skepticism
Just because a belief is popular doesn’t make it true. Examples range from cultural myths like 'fan death' to obsolete scientific theories. The scientific method’s emphasis on falsification helps correct these collective errors.
The Benjamin Franklin Effect: Behavior Shapes Attitudes
Doing favors for others can increase your liking for them, illustrating how actions influence beliefs through cognitive dissonance and self-perception.
Post Hoc Fallacy: The Trap of False Causation
Assuming that because one event follows another it caused it leads to superstitions and false beliefs, such as lucky rituals or placebo button pressing.
Halo Effect: One Positive Trait Colors All
Physical attractiveness and height bias our judgments, affecting social and professional outcomes.
Ego Depletion: The Limits of Self-Control
Willpower is not infinite; exertion and stress drain it. Recovery through rest and positive mood is essential.
Enclothed Cognition: Power of Clothing
Wearing symbolic attire like lab coats can boost cognitive performance and confidence.
Recognizing these biases is crucial for improving decision-making and self-awareness. The mind’s quirks are natural but manageable with knowledge and practice. This blog draws on the book You Are Now Less Dumb and extensive psychological research to guide you through these insights. 1 3 4
