Seems to get cause and effect backwards. Isn't it more likely that an increase in labor supply (women entering the workforce) had, simply by the laws of supply and demand, decreased wages?[1] [1] https://www.dol.gov/wb/stats/NEWSTATS/facts/women_lf.htm#one
The paper is full of complicated-looking economic models and nice graphs-- but if you don't get the basic assumptions right it's hard to trust the fancy models.
edit: The point I'm making, perhaps too tersely based on the below response, is a flawed study can be designed where every outcome would be "surprising" but obviously the rationale supporting that outcome would be poor. That people tend to share surprising outcomes (ie-- post it on Hacker News)-- makes it genius marketing.

I find it odd that the paper cites so many theoretical problems with "5 whys" and then elevates these other methods as preferred solutions without any discussion. It's possible RCA committees already recognize the limitations of "5 whys" and use it as a heuristic that helps focus their efforts. That doesn't mean these committees all sit around a table and say "well, X sounds like a major problem, but it doesn't fit our '3rd why,' so we have to ignore it."
