Why You Knew Better and Did It Anyway

Nobody assents or endorses to an impression they judge to be false.

Nobody chooses the option that looks worse to them at the moment of choosing, which means every decision you've regretted made complete sense to the person making it.

And that person was, of course, you.

And you weren't lying to yourself.

You were running a different valuation at the time.

So the question isn't why you failed to act on what you knew.

It's why, for roughly 90 seconds, you knew something else.

George Loewenstein calls this the hot-cold empathy gap.

In a cool state, you can accurately describe what you want and how much it's worth.

In a hot state, driven by anger or hunger or exhaustion, arousal or loneliness, boredom, the numbers change.

Not your access to the numbers, but the actual numbers.

George Ainslie's work on discounting shows the same thing, but with more precision.

We don't devalue future rewards on a smooth curve.

We devalue them hyperbolically, which means the curves cross.

At a distance, the larger later reward is genuinely preferred.

But up close, the smaller sooner one wins.

Both preferences are real and both are yours.

And the reversal isn't a lapse in the second self's integrity.

It's just basic arithmetic.

Notice what this does to this story of discipline.

There's no calm, rational you being overpowered by an impulsive you.

There are two states of the same nervous system that price the world differently.

And only one of them is in the room when the decision gets made.
