It's extremely common for people to be unable to project into the future when there is a bias in the way. Anytime you see a blatant failure to look beyond the tip of their nose by a person, it's almost always due to their own biases getting in the way (ie it's irrationality, they're giving up reason in exchange for not having to challenge their own position/s).

The other side of that irrationality coin is 2D extrapolation: a thing happened (or a context is such N), so therefore I shall extrapolate it happening again (once or many times) into the future on a smooth line, so as to fit my bias.
