First of all, stop posting misinformation and conspiracy nonsense on the Covid page.


Secondly. Relative Risk Reduction is the STANDARD scale used for quoting efficacy. Is it NOT some sort of cover-up.

To give an example :


In a study of 10000 vaccinated participants, and also 10000 control group participants. If the control group encountered 100 Covid infections and the vaccinated group 5 infections:

- It would give Relative Risk Reduction of 95%

- It would give an Absolute Risk Reduction of 0.95% (difference in rates, 1% - 0.05%)


Absolute Risk Reduction of 0.95% is not "bad". It is just a different metric.

I will leave it up to the admin. I respect his decision and won't be offended if it's deleted.


I think it's an important point though. Most of the covid/vaccine sceptics I encounter clearly lack the skills to interpret statistics intelligently. It seems to be those without any grounding in maths and the sciences who are most susceptible to this sort of twisting of the facts.

It's very prevalent amongst conspiracy theorists - in many cases it's why they're so easily lead into the conspiracy in the first place. Far easier to watch a few YouTube videos than take time to learn facts from reputable sources, especially when the facts involve maths.


You see it a lot in Flat Earth stuff. Much quoting of physics without any understanding of the basics.

You now see this a lot in politics and journalism too, especially with the contrarianism of the spikedonline crowd which has crept into the mainstream. Instead of working their way towards a conclusion, they start of with a conclusion in keeping with their mindset and work backwards. Gove's ''we don't need experts'' comment has a lot to answer for...

Good points. Due to my background the mathematical/logical fallacy is the first thing that jumps out at me. As well as the obvious incongruity between actual ability, and their own perceived abilities. This bizarrely misguided illusion of superiority.


But of course you're right... a lot of it is wanting to believe something, and then grasping at shreds of "evidence" that appear to superficially support that belief.

Even for most honest people a lot of the statistics are non intuitive. Take the headlines that 50% of Delta variant cases in Israel are from fully vaccinated people. This sounds bad but is exactly what you?d expect with 85% of the adult population vaccinated and a 90% is vaccine efficiency.

Yep - that's the bit we're going to have to live with until the cases fall.

Yes. Quite. And in the example I gave, the "Absolute Risk Reduction" is not particularly intuitive either.. and therefore open to misrepresentation and abuse.

I am wondering why no-one has queried this.

LOL... yeah I didn't really follow the maths there either...


Also, our measures of effectiveness have changed over time. I don't think Pfizer is 90% effective at infection from delta variant.

Not debating the basic principle, Alex. That as more and more people are vaccinated - and given that the vaccines are not by any means perfect - eventually the number of cases amongst the vaccinated could be expected to outnumber those amongst the unvaccinated.
I know that RRR is standard practice but don't you think ARR is what most people would expect? When I found out it as standard practice it made me question vaccines rather than just think everything was fine. But I guess some people question more than others.

No because the RRR describes the effectiveness of the drug... it is an intuitive measure. The ARR incorporates the prevalence of the disease, so has to be taken in context.

Questioning things is fine. It can be healthy, I think.


But you seem rather selective as to which sources to question, and which to believe...

Confirmation bias.

You get it in all sorts of fields where people will give greater weight to "evidence" which backs up their preconceived idea and lesser weight to "evidence" which does not back up their opinion.


Fascinating areas of study, confirmation bias.
