Survivorship bias

by Stephen - 5th November 2022
Everyone loves a success story!

The internet is rife with inspirational stories of how people have beaten the odds and triumphed in their pursuits and endeavours. More often than not, such stories are presented to us in a manner which encourages us to see what these people did right in order for us to learn from their successes and hopefully replicate their positive results. The same holds true for articles which provide "tips and tricks" or advice from prominent individuals regarded as experts in their field. We read these stories to draw inspiration, to increase our knowledge of the field, or perhaps simply as a morale booster to see us through tough times...a bookish pep-talk of sorts. While this could be beneficial, if we focus solely on these success stories, we run the risk of always looking at a one-sided picture, a half-truth.

The stark reality is that many, many stories are in fact, to some degree, failures. However, nobody enjoys reading about how difficult it is to achieve our goals, or how many people have already tried and failed at doing exactly the same thing we are trying to do. Besides being a hit to our morale, we tend to think that since they must have done something wrong, they aren't the ones to learn from. So we look towards the celebrity figures as the sole source of wisdom.

What we fail to realise is that failures probably offer us much more valuable information than the successes. By seeing where things went wrong, we learn how to avoid doing the same mistakes. I'm not saying that we should focus on the negative rather than the positive. That would still be the same issue, albeit in reverse. One must have a healthy dose of both and look at all the available information.

Naturally the issue is much more complex than that, but the basic concept is that we must not blindly separate the winners from the losers or even fail to recognise that there are, in fact, losers in every scenario.

If you're not one to be deterred by lengthy articles, I strongly suggest you read David McRaney's article on Survivorship Bias. It's a very interesting read and extremely well written.

So if you're trying to start a profitable business and are in the process of understanding what works and what doesn't, make sure you don't fall victim to survivorship bias.
