• Apo­phe­nia – Ten­den­cy to per­cei­ve con­nec­tions bet­ween unre­la­ted things
• Dun­ning – Kru­ger effect – Cogni­ti­ve bias in which peo­p­le assess their cogni­ti­ve abili­ty as grea­ter than it is
• Finagle's law – Anything that can go wrong, will — at the worst pos­si­ble moment
• Law of tri­via­li­ty – Focu­sing on what is irrele­vant but easy to understand
• Peter prin­ci­ple – Con­cept that peo­p­le in a hier­ar­chy are pro­mo­ted until no lon­ger competent
• Sturgeon's law – Nine­ty per­cent of ever­ything is crap
• Pareto_principle   "The 80:20 rule"* 

* The last 20% to reach a goal take 80% of the total effort. Also, to rai­se a cert­ein amount of money: 80% of the funds will be dona­ted by 20% of the donors. [Wouldn't it be per­fect to know who the­se "20%" are?]
