I am surprised that this blog post went through legal including this detail (<a href="https://archive.md/ZD1zc" rel="nofollow">https://archive.md/ZD1zc</a>): In the next paragraph they write the fraud rate "on the order of 1 out of every 1,000 payments.", so their false positive rate is as high as the fraud rate.
This is a horribly editorialised title. In my view (as a e-commerce store owner) a false positive rate detecting fraud across their whole network of only 0.1% is very <i>very</i> low. If I'm reading it right, that's 1 in 1k <i>blocked transactions</i> are incorrect, not 1 in 1k all transactions!<p>> The challenge is compounded by the fact that fraud is rare—on the order of 1 out of every 1,000 payments.<p>So 0.1% of 0.1% (0.001%) of transactions are incorrectly blocked.
> Out of the billions of legitimate payments made on Stripe, Radar incorrectly blocks just 0.1%.<p>Or rephrased:<p>"Stripe wrongly blocked millions of payments." What a headline!<p>Let's see which news outlet will use it.
