Welcome back to the FiveMinuteFriday episode of the SuperDataScience Podcast!
This week I talk about a costly cognitive bias.
Research indicates, algorithms trained on high-quality historical data predicted the future better than human forecasters were able to. Despite this, people are often afflicted with a common cognitive bias called algorithm aversion which is a preference for a forecast from a human, despite the high potential for error in the human forecasts. People are even more likely to be averse to algorithms after they’ve seen the algorithm perform, even if the algorithm outperforms a human.
In 2015, research out of the University of Pennsylvania found this is rooted in people losing confidence in an algorithm quicker than that of a human when the algorithm and the human make the same mistake. My take-home message from this is for you to check yourself when you find yourself being wary of an algorithm, especially if you can “show your work”. If you’re working on a team with people who seem to be showing signs of this, kindly point out the cognitive fallacy in this line of thinking.
