What if someone claims their p=0.05 but their control group wasn't quite as representative as they assumed and their p is really something more like 0.1?

Or what if one of the experiments in a paper is well-designed and well-executed and supports a hypothesis with very high certainty but some of the other experiments were sloppy or botched? Should the conclusions of the entire paper be labeled as "wrong"?

I find it pretty funny when critiques on statistical rigor in science arrive at language with words such as "mostly" and "wrong".
