Question

In the latest wave of coronavirus, the state's guidelines were relatively more lenient than in the previous waves, and the reason they gave was that although this wave was more contagious, it was less deadly, and therefore there was more room to be lenient.
A friend of mine argued—and it seemed quite plausible to me—that the reason for the leniency was more political than professional, and that in truth it was appropriate to be much stricter than the lenient guidelines that were given. He himself really did go out very little, and even when he did go out he made sure to wear a mask even outdoors.
When I came to figure out for myself what the right thing to do was, I ran into three problems:
A. I don't really have data to check whether reality is in fact more severe than in the previous waves, and to what extent the situation is bad, and I also don't have the tools or the time to start looking online for graphs and reliable information.
B. Even if I did know what the reality was, I don't know how much stricter it is right to be and how much to limit myself, and where to draw the line from which I say that even though this harms the environment around me, it still isn't enough to justify restricting myself.
C. Even if I answered the first two questions, I don't have the medical knowledge to decide what restrictions to place on myself in a way that would improve the situation. For example, it could be that even if the situation is severe, there is no need to go into lockdown, and it is enough just to wear masks.
In general, all these decisions are usually made by experts in the field, and I don't really have the ability to do their job on my own without training.
Because of this, I decided that although in my opinion the guidelines were questionable, because of the doubt I would stick with the state's guidelines.
I wanted to ask whether the problems I raised are indeed valid problems, whether there are additional issues that should have come up in making the decision, and whether in your opinion what I ultimately decided was correct.
P.S. I think this could also be a general problem in decisions in other fields, and not דווקא in the case of coronavirus.
