This is an old 2010 article. It may have been either discredited or updated by now. But the idea that young adults (ages 18-25) can be affected by this is intriguing, because it might support the suppression of derogatory terms and names    But does the same thing happen after that age range?

It's also the sort of report that gets grabbed and quoted by folk for their own agendas.. Quantum Mechanics (usually called Quantum Physics" by its appropriators)  used to be one of these, used to support all kinds of unlikely conclusions. In practice it's akin to quoting the 10% of the brain" myth - an appeal to authority  which relies on people's ignorance of the the source.
