“Metrics”

This reminds me of a past job working for an e-commerce company. This wasn’t a store like Amazon that “everyone” uses weekly, it was a specific pricey fashion brand. They had put out a shitty iOS app, which was just a very bare-bones wrapper around the website. But they raved about how much better the conversion rate rates were there. Nobody would listen to me about how the customers that bother downloading a specific app for shopping at a particular retailer are obviously just superfans so of course that self-selected group converts well.

So many people who should be smart based on their job titles and salaries, got the causation completely backwards!

Hey, I notice this kind of thing all the time. People use "data" to tell the story they want to -- similar to how it seems humans make a decision subconsciously then weave a rational decision to back it up afterwards.

Do you have principles on how to tackle this? I feel stuck between the irrationality of anecdata and the irrationality of lying with numbers. As if the only useful statistic is one I collect and calculate myself. And, even then, I could be lying to myself.

This stupidity might go a long way towards explaining the relentless push towards apps.
