How Effective Are Masks and Lockdowns at Controlling Covid? Take the Covid Charts Quiz to Find Out.

You can have correlation without causation, but you can NEVER have causation without correlation.

If you’ve wondered about the effectiveness of masks and lockdowns and whether or not lockdowns, mask mandates, or high masking compliance made a meaningful difference in slowing the spread of covid-19, I encourage you to check out the following charts and quizzes at the link below. Most people understand that correlation does not equal causation and that it can often be difficult to prove causation. This is especially true when there are almost limitless factors that cannot be controlled (hence the importance of randomized controlled trials (RCTs) and other studies that help us distinguish correlation from causation). That said, when it becomes impossible to even show correlation, proving causation is out of the question. Put differently, you can have correlation without causation, but you cannot show causation if there is not any correlation. If you want to see if there is even any correlation between lockdowns and masks and a reduction in the spread of covid, especially in comparison to places that never imposed mask mandates and that did not lockdown, take a look through the following charts at the quiz site below:
