Speaking of Monte Carlo, here's a paper about how using bad randomness can lead to wrong simulation: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2992609/ (or should I call them _biased_ ones?)

And as a counterpoint, if you use a well-chosen deterministic sequence, it can make some Monte Carlo methods produce better results faster than true randomness would (quasirandom sequences and all that).

So, interestingly, "bad randomness" =/= deterministic.

(not that you were claiming that, just adding this subtlety to the mix)
