Contagion with opposing postulates happens all the time. The school system is designed to produce “good “ citizens who go to work and pay taxes because it is the right thing to do. But if you see that the government is corrupt then paying taxes is the wrong thing to do.
A kid falls in love with a certain girl but she rejects him and he decides he is no good.
A team has a loosing season and decides that they are second rate players.
All of these are contagion by opposing postulates. Life is full of them.

Like when I make optimistic conjectures only to be automatically countered with negativity over and over again, until I "learn".
