I read your comment as strongly sarcastic. Do you mean it that way? Because it looks to me like they are very up-front about how iffy some of this stuff is. So what's the problem?
The trouble with self-help advice is that it’s often based
on barely any evidence.
... [however] we’ve found that there are a number of
evidence-backed steps that anyone can take to become more
productive and successful in their career...
So we’ve gathered up all the best advice we’ve found over
our last five years of research.
In many cases, the evidence isn’t as strong as we’d like.
Rather, it’s the best we’re aware of. We’ve tried to come
to an all-considered view of what makes sense to try
Even if you are up front about how iffy your stuff is. You cannot just call out 'self-help advice with barely any evidence' and then repeat said advice without batting your eyes.
I was hoping to see some actual evidence, but instead I found product advertisements and cheap motivational shit.
