Some questions naturally occur with this line of inquiry. If you don't know why you are doing something, is this the same as willfully ignoring the reason? I would suggest yes. You should have a moral reason to do the things you do. If reasons to possess a certain behavior are proven wrong later, you have a reason to change your behavior, and not taking this action shows dependence on the behavior. Does the broaden the range of addiction? Sure it does; even people who take vitamins after the suggested benefits are disproved are showing an addiction to the habitual action (and possible placebo effects of) that behavior. Isn't there a fine line between procrastination and ignorance? I would suggest that the perfection effect (being paralyzed by inability to perfect the task you're attempting) is a struggle between procrastination and ignorance, and is really just using ignorance to cover for your procrastination. This is indicated by the ease in which ignorance is cured (by research) as opposed to procrastination (where said research turns into aimless wandering).
Finally, after looking at these negative conditions, doesn't the Venn diagram seem kinda lopsided? It could be an effect of the internet; the increasing ease in which ignorance is curable allows for the other parts of the diagram to dominate. Something to think about.
