Most of these are really good, especially productivity and time estimation. Some I do not agree with (although perhaps the model presented is useful depending on desired outcome). -Efficient market hypothesis: Markets are not fully efficient and the state of the world is not optimal. Thus opportunities exist. It's our job as engineers (and business people/humanitarians/writers/philosophers etc.) to recognize and correct these inefficiencies. Look for them. Its not easy and thus is called work. Do it anyway. -Base Rates: People are over-optimistic. They are also bad at finding similar things to compare. -Emic vs Etic: Dangerous form of mental laziness. While it might be "efficient" it leads to underestimating people and phenomenon, missing out on valuable information and, as the old saying goes, judging books by their covers. Sometimes valuable lessons and opportunities can be found in strange places. And often it isn't even what is said or even "anti-lessons". Better to remain somewhat open and listen without preconception and with consideration as much as possible. -Bias for Action: Unsure about this one. Looking back I'm not sure if I regret more actions I didn't take or actions I took that were mistakes. I think probably the second has had more negative impact. But I've been a fairly active person, maybe for a less active person it would different. In my case though very often doing nothing would have been the better choice. -Charitable interpretations: These do make relationships go better. Especially for people who take advantage of others. I'd recommend outward charitable interpretation, inward cynicism. It's usually more accurate for prediction. But cynicism does make a person unpleasant and negative so best not to display it. -Global Utility: A dangerous precedent. But sometimes yes, indeed needed. Be extremely careful of deals with the devil though and prefer principal, honer and fairness as much as possible. The long term gains are usually greater. The long term effects of short term utility can sometimes be fatal. -Reasonable Person Principal: Meh "reasonable" can be whatever a group decides. It's not always good. However, no need to keep someone around who doesn't fit the agenda. Hopefully you don't see them in the 30 under 30 list in a few years though. Otherwise it's a pretty good list.
