Actually they did a study on the masks and proved effective.

It was done by picking a population of 350K, then separating them to test and control groups, encourage mask for the test group.

The results are that at 39% mask use in the test group the covid cases were %12 lower than the control group.

There was also a difference between surgical mask(%12) and cloth mask(%9) use.

No actually required :-). I didn't say masks were not effective, I said part of their effectiveness is the making-conscious of transmission vectors. E.g. when you wear a mask and see others do it you are more likely to wash your hands or stand back.

When you wear a mask (as I do) in addition to blocking some particles you signal to others "lets play the not kill eachother game by limiting virus vectors!"

Fair enough:) They should also made some of the test ground really chill to see if it is the mask or the attitude!
