Karl Popper had described science as a (virtual) place where things happen like this:

Some guy has an inkling. Studies it and gathers a lot of information on the subject.
Based on that information, develops a hypothesis. Then attempts to prove it.
After being satisfied with how much proof they had found, the hypothesis is declared a theory. And published as such. Along with all pertinent evidence. For all those interested to see.

So that all those interested to be able to replicate the experience.
To be able to retrace the proving process. To certify its validity.

And for all those interested to be able to find any proof to the contrary!
So that, as soon as that proof had been found – and declared acceptable, the theory to be considered false. Or, at least, incomplete.

The first example which comes to my mind being that the simple existence of Einstein’s Relativity had proven that Newton’s Physics was incomplete….

Fast forward to our days.
To our raging Covid-19 pandemic.

When vaccines are already available and where there are people who refuse to be vaccinated.

The vaccine was supposed to protect us.
From becoming infected.
From needing to go to the hospital.
From dying. From ending up suffocating alone…

But people continue be infected. Even after receiving the vaccine.
People continue to be admitted to the hospital.
And people continue to die. Even after receiving the vaccine.

Wouldn’t all these evidence strongly suggest, scientifically speaking, that the vaccine is useless?
‘Useless’, to say the least?

Wouldn’t it be actually rational to frame the situation in these terms?

Well, according to Popper’s reasoning, the first vaccinated individual becoming ill had been ample enough proof of the fact that the vaccine was not 100 % foolproof. That it isn’t fail-proof!
The first vaccinated individual being admitted to the hospital had been ample enough proof that the vaccine is no absolute shield against any of us who has been infected will ever have to go to the hospital.
The first vaccinated person who had died with Covid-19 had been ample enough proof that the vaccine will not protect all of us from dying after becoming infected with this virus.

And the fact that so many of us continue to refuse to be vaccinated is ample proof of the fact that reasonable should trump rational. Yet it still doesn’t….
Of the fact that too many of us continue to consider that their short term/self serving interests are more important than other people’s lives.
And of the fact that too many of us continue to ignore how vaccines work.

The key aspect here being the last!
People continue to ignore how vaccines work simply because of the huge amount of disinformation which is being peddled on the internet right now.
It’s not the ‘refuseniks’ who put their short term/self serving interests in front and above the lives of innocent people!
It’s those who have initiated, and continue to drive, the fake-news process who will be eventually determined as having been the root-cause of the excess mortality we’re currently experiencing.

When?
Hopefully, after a reasonable amount of time.
If enough of us start behaving rationally… In a comprehensively rational manner…

In a truly scientific manner!
