P-hacking and flexibility of solutions
When a researcher runs through criteria, filters, and models until a significant result emerges, he can obtain a publishable conclusion even where there is no consistent effect.
Selective reporting of results
The crisis intensifies when the article includes only convenient variables, successful subgroups and beautiful effects, and not the whole picture of the analysis.
Small samples and low power
Studies with small samples often produce inconsistent effect estimates, so even a significant result may be overestimated or due to chance.

Эта тема раскрывает узел "Репликация исследований" и нужна для того, чтобы карта не заканчивалась общим названием без внутренней структуры.
