Some things that popped into my mind and I decided to write down. They may only apply to me. They may be incorrect. They may be well-known concepts that I’m reminding myself of.

MECE is one of the most well-known acronyms in consulting. Standing for Mutually Exclusive, Collectively Exhaustive, it is a principle used when doing any form of segmentation, to ensure no duplication (ME) or missed items (CE). This exists in a bunch of scenarios, such as solving problems, writing documents, and preparing presentations. There are countless articles explaining what it is, so I won’t go into too much detail. These often include a Venn diagram or two to show ME and CE, but I haven’t seen them used to demonstrate the whole MECE concept - so that’s what I thought I’d do.

I thought I’d have a play with ChatGPT, to see if it could help me write about, and refresh my knowledge of, logical fallacies. I also wanted to test some of the various “bugs” I’ve been reading about (for example, it’s terrible with numbers). I asked it for a list of common logical fallacies, then asked it to provide definitions and real examples from political debates. The answers are copy-pasted from ChatGPT with minimal editing.
