I've read and seen the methods behind these mask vs non-mask studies and they primarily focus on sneezing and coughing. It assume maskless people don't cover their mouths or turn away. This is never the case. Highly flawed subject behaviors.

Because it spreads not just from coughing and sneezing but talking. Which is why masks work. People aren't covering their mouths while talking.
