This shit will not replicate. Classic p-value hacking, if not total fiction, dreamt up to pad chum buckets. It is junk science to the core. I'd bet one thousand dollars that another researcher could wrangle contradictory data with a diametrically opposed result. This trash infotainment has been selected because it is inconsequential to the point of being astrology. No individual can take this "discovery" and apply it…
I tend to be reflexively skeptical of results like this as well - but I also have a lot of time for results from the Dunedin study. Long-term studies are great and we (society, science) should do more of them.
