Overview

Matt Parker of Stand-up Maths examines scatter plots that were claimed to show fraudulent vote-switching in Michigan's 2020 election. He recreates the analysis and shows that the pattern arises from comparing percentages across different bases, not from fraud.

On Hacker News

HN commenters cite it as a clear debunking of election-fraud statistics and as a warning against comparing percentages without context.

Don't. Compare. Percentages. Stand-up Maths called this out recently and it's good to mention. I think this might be the video: [VIDEO] Give me the output and our total consumption please.

The way this is presented is going to be interpreted incorrectly. It is incorrect to compare percentages or probabilities like this. Here is a different example to try and illustrate the problem: Is 10% larger than 5%? It is not possible to answer this question if the basis on which the percentages are calculated are different. What if I said the 10% was 10% of whatever you last spent money on, but the 5% was 5% of Google's annual revenue. Which is larger? The same thing is happening in the above - it isn't okay to calculate the probabilities in two situations and then try to cross compare them for size. Sadly this error seems to be cropping up quite a lot! Matt Parker (Stand-up Maths) has an example of this and related to a recent election: [VIDEO] . His explanation is likely better than mine.

I really hope something is done against Dr. Shiva Ayyadurai's content. He's been posting highly misleading/disingenuous election fraud material in order to gain a following, and people are believing it because he touts his PhD from MIT. Honestly at this point between his senate run and "Inventor of Email" scandal I'm surprised MIT hasn't had a response. For example, here's a video that debunks many of his claims: [VIDEO]
