Your reading comprehension is always so much weaker than your math.What do you mean “something works or it doesn’t”?
Can you honestly not think of anything in the world which is only partly efffective? Mousetraps. Anti-lock brakes. Weather forecasts. Does this mean they are all useless?
You love your false dichotomy fallacy so much, you are insulting others for not copying it.
I said you have to define what”work” means. It either meets the standard or it doesn’t. But it’s up to you to lay out that standard (which the complaint recently is that it shifted majorly with the arrival of the delta). We went from vaccines 95% effective at stopping transmission and it would be over by June to now we don’t really know (which is why you are back on masks on the vaccinated)
And having been caught in a thunderstorm which unexpectedly wiped out goalkeeper practice and team practices Monday, I don’t think most people would say weather forecasts “work” but again it depends on the definition.
