How Anecdotal Evidence Can Undermine Scientific Results

Something to watch for - both in self and in others.

Blame it on evolution — we’re not perfect! Some quotes from the article:

“Our brains have evolved to live in the moment…”

“Most pleasure springs from the ancestral, reflexive system…”

“Thinking of the brain’s pleasure system as a kluge…”
