Confirmation Bias
Once you believe something, you start noticing evidence that agrees with it and quietly skipping evidence that doesn't.
In Practice
After buying a stock, it's easy to read only the bullish articles about it and skim past the warning signs — the belief came first, the "research" just confirmed it.
Generic Example
Once you decide you don't like a movie five minutes in, you start noticing everything wrong with it and stop noticing what's working.
Am I actually testing this belief, or just collecting reasons I already wanted to be true?
