In reverse

Science doesn't work in the direction of trying to prove a hypothesis. It actually works in the direction of trying to disprove it. 

We notice a phenomena, propose a theory and go about, in a sense, trying to disprove it through experimentation. The aim is to make sure we don't infect the process with wishful thinking and bias. 

Pseudoscience works in reverse in that it proposes a theory which it then spends all its time looking for shreds of proof to bolster. 

The earth is flat and that's all there is to it. Don't bother me with evidence to the contrary.

In pseudoscience the bias is baked in and once enough data points exist to the satisfaction of the true believer, they can stop there despite the existence of gaping holes.
