Hunger, Blood Sugar & Judgment
Hunger raises negative affect and irritability and shifts people toward immediate rewards; the popular 'willpower runs on glucose' story is not supported, but the mood and impatience effects are.
An everyday example
Reviewing a contract at 1 p.m. with no lunch, you find every clause hostile and want to end the call.
What it can cost you
Reading your own hunger as the counterpart's bad faith, or choosing the fast option to make the discomfort stop.
Warning signs
- Everyone seems difficult today.
- I want the decision over more than I want it right.
One thing to do
Eat before anything that matters; if you cannot, defer the decision rather than decide hungry.
