Failing Upwards

Survivorship bias often gets discussed as a cautionary tale. For example, someone might point out a person’s or company’s success, and another will retort with, “But that’s just survivorship bias!”. People don’t often discuss how to internalize survivorship bias in an actionable way. In other words: if you know that most people who win the lottery in some fashion (whether in business, investing, dating, or even the actual lottery) did so mainly out of luck, it doesn’t answer the question of how we can use this information to our advantage.

Thinking Slowly

In Daniel Kahneman’s pop psychology book Thinking, Fast and Slow, he describes the human brain as having 2 systems for thought: a fast system, which responds quickly to stimuli, and a slow system, which tends to produce more…thoughtful thoughts. This book was all the rage amongst thought leaders circa 2011/12 after being published, but if you missed out on it, don’t worry, Wikipedia has a tl;dr which tells you all you need to know.

Software Developers Aren't Special

Software engineers tend to be smart people. Writing software is hard, and it’s entirely a discipline of exercising your brain cells to write the correct commands to make the computer do what you want it to do. Add in the layers of complexity that come with dealing with humans who want software to do something without necessarily knowing or understanding precisely what they want, and what you end up with is a fairly complicated practice.

Random Walks

·3 mins
Life is a series of random walks. Even if you walk the same path every day (in the literal sense), your individual steps on every walk you take are essentially random, and for the most part you aren’t even conscious of them because this is handled by muscle memory. When I say the steps are random, what I mean is that if you could precisely measure every step you take, where your foot lands, how much force you apply with your individual muscles to all the components of your leg and foot and torso and so on, the data would appear to match a pattern from a statistically perspective, but each individual step would have a normal random distribution.
