Anyone can find studies to support either side. I'll say it again, the messaging with wearing mask creates a mentality in many, I bet the majority, of mask wearers of a false complacency. We saw it with the riots, I mean protest, there was zero social distancing, highly doubt they were passing around hand sanitizer yet many defended it by saying "most were wearing a mask", give me a break.It does appear to be effective but it is far from 100% (nothing is near 100%) and it also depends on the correct wearing of it. The goal is a reduction in virus coming from mouth/nose. Any reduction is good.
