I feel like misclicks don’t get much consideration. I know I personally misclick on a little less than 1% of posts I look at, usually because I’m scrolling quickly or transferring my phone from one hand to the other or something, and end up fat-fingering the button. Sometimes I notice and fix it, but I know I don’t catch all of them. I do put a little bit of effort into being careful though, I know not everyone does.

For this reason, I always consider that maybe 1-5% of total votes might potentially be misclicks, or just people not paying much attention, and I don’t really consider them. I figure misclicks will be split 50/50 between up and downvotes, with the downvotes being much more noticeable in general, due to human biases towards negative reinforcement.
