<p>This seems to happen far more frequently than one would expect from a Poisson distribution with a ~10 minute mean. Am I just bad at statistics or is something else going on?</p>

Upvoted, it'd be interesting to see the probability of, for example the next block being made in under a minute. (I think that has the probability of 0.095 according to [this](https://www.wolframalpha.com/input/?i=integral+0.1e%5E%28-0.1*t%29+from+t+%3D+0+to+t%3D+1), with the help of [RC](http://r6.ca/blog/20180225T160548Z.html)'s blog though I'm not knowledgeable enough to write an answer.)

Is your "this seems" based on calculations, or just a guess?  If calculations, would you like to share them?

I haven't done any calculations, just a guess from something I noticed. Would be interesting if anyone felt inclined to put together some actual numbers

I can produce some statistics based on the block timestamps if it would be of interest, but given that they do not necessarily correspond to the time at which the blocks were mined or broadcast, I don't know if that would be helpful.

Why do we often see 2 blocks mined within a few seconds of each other?

Maybe.

AFAIK Mining nodes don't synchronize time. Timestamps in blocks are not accurate. You cannot tell the elapsed time between two blocks by looking at timestamps in those blocks.
