The Science of Decision-Making
CantDecide.org does not teach, mentor, diagnose, or claim to know the right decision for anyone. We do not provide personalized advice. We share our own thoughts and observations about human thinking and decision-making, alongside accessible summaries of publicly available scientific knowledge.
Where possible, we will link readers to original scientific papers, universities, research institutions, and other authoritative sources. Our aim is to encourage curiosity and critical thinking so readers can examine the evidence and reach their own conclusions. No research, statistics, quotations, authors, studies, or citations will be invented.
