Elaborate. Your "in the 20% range" claim seems to be incorrect, according to your own source, and missing context: research in other fields like medicine faces similar issues.
In psychology:
> In August 2015, the first open empirical study of reproducibility in psychology was published [...] Of 97 original studies with significant effects, 36% replicated successfully (p value below 0.05)
In medicine, for comparison:
> Of 49 medical studies from 1990 to 2003 with more than 1000 citations, 92% found that the studied therapies were effective. Of these studies, 16% were contradicted by subsequent studies, 16% had found stronger effects than did subsequent studies, 44% were replicated, and 24% remained largely unchallenged. A 2011 analysis by researchers with pharmaceutical company Bayer found that, at most, a quarter of Bayer's in-house findings replicated the original results. But the analysis of Bayer's results found that the results that did replicate could often be successfully used for clinical applications.
Ah it looks like somebody has been ideologically editing Wikipedia. Shocker. Here [1] is an archive from a year or so ago, referencing/citing the 23% for the Journal of Personality and Social Psychology. I should probably look to finding a more stable and reliable source for information/citations than Wiki.
