The best we can do is trust what is verified

Scientific knowledge is both complex and simple. At best it is temporary truth, forever flirting with fallacy, ever encouraging emendation.

It can be quite confusing sometimes. Current COVID-19 recommendations engender questions and controversy. The rationale for adopting protective measures is clearly misunderstood.

Masks and social distancing are not designed to protect the person employing these measures. The protocols are intended to protect others. Why should you care? Recall the Aesop tale of the lion with a thorn in his paw. Years later the favor was returned.

Some declare that the rules are a violation of personal freedom, are unconstitutional. Maybe so. But keep in mind that death is the ultimate infringement of "your rights." Do you want to risk it?

Mixed messages abound.

At first, masks were discouraged, now it is de rigueur. "Facts" change. The most recent meme drives public opinion. Factions argue prudence vs politics. Skeptics question data interpretation. Others deny the problem altogether.

Scientific knowledge is often uncertain. COVID-19 is terra incognita.

The best we can do is to go with what can be verified, to encourage best practices, and be open to fresh ideas. There is much to learn and little time to do it. Certainly, we do not know enough. Choose your sources carefully. Beware the all-knowing. They are incapable of learning and they are extremely dangerous.

Do your best right now. Practice restraint and follow sensible recommendations. Utilize responsible sources as a basis for your decisions. Most importantly, keep learning. You know how.
