1 Making Decisions

2 How can we research decision making?

3 Making Decisions Decisions can be very diverse E.g. Palestine/Israel What to have for breakfast Whether to work or play

4 Operationalise Need to measure our decisions Reduce to ODDS Set of scenarios Choice between safe and risky

5 Example Friday night, Could sit and watch tv (safe) Or go to a show (risky)

6 Going to a show Haven’t got a ticket It’s raining What determines what I will do? If performer is fabulous or is mundane

7 Going to a show If fabulous will take risk Even if 1 in 10 getting a ticket is worth the risk If mundane, then TV looks better Maybe odds need to be 8 in 10 (or 10 in 10)

8 Odds By using odds can compare Note that the lower the odds, the more risk you are accepting, because you find the alternative choice attractive High odds mean safe option is as good or better than alternative
