Initial Braindump (hopefully will edit)
Knowledge dependencies (algebra before calculus)
Necessary tools? (Did people who made simultaneous discoveries use the same tools?)
The research community for that domain? (How much communication is there? How dense are the connections between people?)
How new the field is. Whether there was a sudden jump in the number of researchers.
How frequently discoveries happen in the field.
Whether a major disaster or other event is obstructing scientific progress from being made at the time.
Whether the existence of simultaneous discoveries is just an artifact of cherrypicking biases
