The difficulty of this little scientific endeavour would be that you would need to have enough people that only use open source social media over a sufficient period of time that you could monitor and record responses/behaviour.
But people can’t be trusted and they would inevitably look at other socials which would then dilute your results.
If you did manage to get a study completed you would then need to submit it for peer review (as with all studies) to the scientific community as a whole and they would need to perfrom their own tests to compare results.
Nope, there is none.

So, you can see the difficulties.
