Group one, lost a ticket, and must buy another one, but group two lost the
ticket value before in the day. We find that group 2 people will more likely to
buy the ticket, even though they lost the same amount of money.

## Document Summary

One sentence can only have one surface structure, but there can be more than one deep structures. Insensitivity to sample size: representativeness, availability, concrete information, framing effects. Group one, lost a ticket, and must buy another one, but group two lost the ticket value before in the day. We find that group 2 people will more likely to buy the ticket, even though they lost the same amount of money. It"s how we frame the question to solve problems. Graph him going up and graph him going down, when the two lines intersect is when he was at, same time when he was going up and down that he had passed. Lily problem: there"s 1 lily in the pound, on day 60 how many days does it take for the pound to be half covered. Correct solutions to insight problems involve: selective encoding, selective combination, selective comparison.
