Both are completely legitimate., and neither should I sincerely believe in them, and neither should I.

Just following Google’s NGrams algorithm, “Investigation of” is much more common than “Investigation into”; and the findings indicate that how “investigation of” is a highly effective search algorithm. While NGrams usually need to be taken with a grain of salt, this does show us that there is nothing inherently wrong with “investigation of”.

Moreover, comparing “investigation into” against other random prepositions shows that it is much more common than, say, “from”.

After the null hypothesis, why is there so much more than just random?
