Daily Productive Sharing 425 - How to Deal With 80/20 Rule?
One helpful tip per day:)
Pareto's law, also known as the 80/20 rule or the power law, is a law that we often encounter in life, such as 80% of wealth being owned by 20% of the population and the remaining 20% being owned by the remaining 80%. Although it seems to be a law that we are familiar with, Ben Kuhn details how to understand it and how to optimise its output in our life:
- Because heavy-tailed distributions are unintuitive, people often make serious mistakes when trying to sample from them:
- They don’t draw enough samples
- They underestimate how good of an outcome it’s possible to get
- They find it hard to tell whether they’re following a strategy that will eventually work or not, so they get incredibly demoralized
- The most important thing to remember when sampling from heavy-tailed distributions is that getting lots of samples improves outcomes a ton.
- This means that sampling from a heavy-tailed distribution can be extremely demotivating, because it requires doing the same thing, and watching it fail, over and over again.
- An important thing to remember in this case is to trust the process and not take individual failures, or even large numbers of failures, as strong evidence that your overall process is bad.
- Some amount of optimization is worth it, but most people are way over-indexed on optimization and under-indexed on drawing more samples.
- One thing helpful is to ask other people what outliers have looked like based on their experience.
- So what does a good process for searching for outliers look like?
- Take lots of shots on goal. The more samples you have, the more likely you’ll find an outlier.
- Know what to look for: try to figure out how good of an outcome is possible, so you know when to stop.
- Find ways to evaluated candidates that are well-correlated with what you care about. Filter for “maybe amazing,” not “probably good.”
- When possible, try to sample and evaluate candidates quickly, so that you can iterate on your sampling process more quickly.
- Don’t get discouraged when you do the same thing over and over again and it mostly doesn’t work!

帕累托定律，又称为80/20法则或者幂定律，是我们在生活经常遇见的定律，比如80%的财富被20%的人拥有，而剩下的20%被其余的80%人拥有。尽管这似乎是我们熟知的一个定律，但是 Ben Kuhn 详细介绍了如何理解这一定律，并在生活中如何优化这一定律的产出：
