Irrationally Influenced Rational Decisions
How do we make decisions when the outcomes are uncertain?
One possible way would be to calculate the expected value of each option by multiplying each possible outcome amount by its probability and then choosing the option with the highest expected value.
While this strategy would maximize the payoff in expectation, this is not what we tend to do. In particular, we seem to be irrationally influenced by past outcomes of our decisions when making subsequent choices.

How A Lucky Win Skews A Known Probability
Specifically, the researchers asked 70 people to repeatedly choose between two lotteries in which they could gain some reward with some probability. The lotteries varied in the size of the reward, the probability of receiving it, and the amount of risk involved.
The results showed that

Expected value
We all spend time making decisions with some risk involved. We look at each situation and consider the likelihood that something will happen as well as if it would be worth it.
For example, whether to sprint across the street when the sign says “don’t walk.”

Good decisions
To make good decisions, we generally need to do the following:
- Identify the decision: recognizing the need to make a decision, and identifying what that decision involves.
- Set our goals: establishing what we want to achieve with the decision...
