decision making

Your brain prioritizes immediate comfort over future success.

A 1981 study found that pigeons consistently prefer a small reward now over a larger one in the future.

The Ainslie and Herrnstein (1981) study utilized pigeons, not human subjects, to demonstrate preference reversal.

Your future self always loses in the current moment.

Where this comes from

Study: Ainslie (1975), Hyperbolic Discounting
What the check found: The 1981 study specifically used pigeons. While the theory of hyperbolic discounting applies to humans, citing that specific study as the evidence for human behavior is factually incorrect.
Confidence: Solid, with limits

One of these every day, and every one names the study it came from. When a finding is contested, it says so.
