Observing the distribution of the numbers in a number system other than 10 and comparing the unevenness observed there to that observed in base 10 could also form the basis of testing for human intervention into the natural behaviour.
Sympathetic numbers in base 10 should look more random and even in other bases.
Particularly, 11 and 9 may not be that bad candidates. Although, if the numbers deviate slightly around a center then it may not be too different from what was already observed in base 10.
7 and 13 seem at first good candidates (noticeably different (relative) primes).

What last digit distributions would we get then?
