How does rational decisions making occur?

Answer 1

Digitalize all the relevant factors according to their importances and the net effects.

Should I go to my friend's birthday party?

If no, my friend will be mad: 10

If yes, I can not complete my homework project:

a. My teacher will be angry but will give me another chance: -3

b. My parents will be furious and keep me home for one month -10

If yes, I will meet some old friends there: 8

If yes, there will be some favorite games: 6

If yes, I can not prepare my science exam next day

a. I may get B instead of A: -5

b. I will not have Chrismas gift due to the B: -2

c. My parents will not let me go to any party: -10

Now tally the scores: -6

You should not go.

However, if you work on completing your project and preparing the exam well before the birthday party, the scores will become favorable. Then you can go.

I hope that the strategy can be helpful to you.
