The essential idea
Tom Chatfield presents critical thinking as a constructive method for improving decisions, not skepticism for its own sake. A claim can be examined through its thesis, reasons, evidence, assumptions, counterarguments, and conclusion, making gaps visible before they enter a roadmap, architectural decision, incident narrative, or people decision.
Sound logic is not enough when the input is weak, so the method also tests authorship, expertise, collection methods, sample and period, limitations, conflicts of interest, independent confirmation, and context. Alternatives are compared against explicit criteria, with conditions for revisiting the decision recorded in advance to reduce confirmation bias and groupthink.
Decision lens
Key takeaways
A strong argument separates its thesis, reasons, evidence, assumptions, counterarguments, and conclusion.
Source quality depends on expertise, method, limitations, incentives, independent support, and context.
Explicit alternatives and criteria prevent the first plausible option from becoming the only option.
Confirmation bias, false dichotomies, post hoc reasoning, and groupthink commonly distort technical decisions.
Facts and timelines should be separated from interpretations in incident reviews.
Critical thinking aims to make a decision more robust, not merely to find defects in someone else's reasoning.
Decisions should include success criteria and observable triggers for reconsideration.
Workplace experiment
Apply it at work
- 1
State the decision question in a concrete, testable form.
- 2
Separate facts from interpretations and create two or three competing hypotheses.
- 3
For each hypothesis, list assumptions, evidence, counterarguments, source limitations, and a possible disconfirming signal.
- 4
Compare options using criteria defined before selecting a favorite.
- 5
Record the decision, success measure, and trigger that would require it to be revisited.
Choose one action, define the observable effect, and keep the first test small enough to reverse.
