Irrational

Why do I want to do easy and instant/entertaining things (like how to best save/grow money in bank account, read predictably irrational) and not hard and long-term things (study PROSE work, TLA+)

The Coin Flip

Sorta from Prospect_theory#Example and http://www.sjsu.edu/faculty/watkins/prospect.htm

Guaranteed $1000 $2500 if heads
Sweet, $1000 guaranteed! $0 if I lose, no way!

Increase reward

Guaranteed $1000 $7500 if heads
Sweet, $1000 guaranteed! Now I don't feel so bad about “betting the house”

Increase flips

Guaranteed 10 * $1000 $2500 for each head of 10 flips
Sweet, $10K! Oh wait…50% * 25K = $12.5K, low variance gaussian, ok, sure

Risk seeking

Guaranteed $1000 loss $2500 loss if tails, $0 if heads
Man, that sucks I have a good chance of this sucking less
Even though it will likely burn you more

Predictably Irrational (book)

Ch 1 When Relative isn't Relative

Why Insurance and Lottery?

One sample from paper

Music Player New Car
Discount $20 / $50 $20 / $20,000
Outcome Man, I need to drive across town to get that deal! Whatever, I'll just get it closer to me. Not worth the drive
“Rationale” Me: I'm going to make a killing into their profit margin / it's a really good deal. It's rare and unusual. They're basically the same price. Why bother? Oh, a $1000 leather seat upgrade, that's not so bad either…throw that on too!
Irrationality $20 is still $20. We think in relative measures to our peril to sales teams.
