Commentary: Reproducibility in Psychological Science: When Do Psychological Phenomena Exist?

This punchy commentary fires back at a researcher who claimed psychology shouldn't worry too much about replication (repeating studies to see if results hold up) because humans are just too complicated. Heino, Fried, and LeBel aren't having it. Their counterargument is delightful in its bluntness: if we abandon the requirement that findings be reproducible, psychology basically becomes astrology. Ouch. They point out that ecology, biology, and physics deal with enormously complex systems too, yet still manage to hold themselves to replication standards. The real takeaway? Complexity isn't an excuse to lower the bar -- it's a reason to design smarter studies, like tracking the same individuals over time instead of relying on one-shot group snapshots. The parallel to parapsychology is striking, since psi researchers often face the same argument that their effects are too context-dependent to replicate reliably.
