Psychological mechanism
Adaptive Transactive Memory. The human brain treats external storage systems (like books, friends, or internet search engines) as seamless extensions of its own memory network. If it recognizes that an external tool reliably holds a piece of data, it refrains from expending the metabolic energy required to encode it into long-term biological memory.

Debrief
Biases are not character flaws. They are recurring patterns in how minds compress uncertainty, save energy, and narrate reality. Once you recognise the pattern, you can slow the decision down, test the assumption, and make space for a better explanation.
