economics, with characters

“for sake of explaining my probably somewhat abstract thoughts and the nature of economics, i will use two different people as guiding characters.”from what's your utility function?
one

a question from life

why do two people make the same choices for opposite reasons? why does admitting you might be wrong feel so expensive?

two

a small model

U=f(M,L)U=f(M,L)
MU(A)=1001+A\mathrm{MU}(A)=\frac{100}{1+A}
P(H∣E)=P(E∣H)P(H)P(E)P(H\mid E)=\frac{P(E\mid H)P(H)}{P(E)}
three

two characters who live it

economic models are illustrative thought experiments unless explicitly identified as empirical evidence.
