Looking for Evidence That Discounts Your Beliefs and Assumptions
Seek evidence that could challenge a belief, then examine the assumptions that depend on it. Revising a central belief can open related views to reconsideration.
THE IDEA
Beliefs can become part of how we understand ourselves. That makes contrary evidence uncomfortable and easy to dismiss. Start by stating a belief clearly enough to ask what would count against it.
Look for relevant observations, including ones your usual sources or habits might hide. If you believe you cannot learn a difficult subject, for example, examine what happened when you had enough time, instruction, and practice. Separate the evidence about a particular task from a sweeping judgment about your ability.
Then consider which other beliefs depend on that judgment. Revising a central assumption may give you reason to reconsider them, but it does not settle every related question or automatically change your behavior. Check each conclusion and decide what you could test next.
When to use it
Personal development: Identifying and challenging self-limiting beliefs to expand capabilities.
Business: Questioning assumptions about customer behavior or employee productivity to improve strategy.
Education: Encouraging students to challenge their own assumptions to promote critical thinking.
Philosophy: Deconstructing foundational beliefs to build a more coherent worldview.
FROM THEORY TO EVERYDAY LIFE
In practice
Intelligence Belief
Someone believes they are not intelligent and therefore avoids demanding tasks. Reviewing occasions when they learned difficult material may challenge that broad judgment. They can then try a specific task with suitable instruction and assess their progress.
Remote Work Productivity
A manager who believes remote workers are less productive examines the team’s actual output, quality, and working conditions. They look for cases that contradict the assumption as well as cases that support it.
A MOMENT TO REFLECT
Put it to work.
What is a core belief you hold about yourself? What evidence might contradict it?
How does this belief affect your actions and decisions in daily life?
Which other belief depends on this one? If the evidence changed your view, what would you need to reconsider?
