Much of such dubious "science" is packaged by self help authours as miracle principles which are going to set ones life right. Popular books like "Power Of Habit" and Cal Newport's books also seem to fall into this category, and seem to enjoy huge patronage, even in HN.
May you please explain what Cal Newport has stated , that is considered "dubious science."
In that sense I find him way better than other authors listed: he actually makes good use of the tools he recommends as a professional (as opposed to making a living spouting bullshit about other people's work).
