While Thomas Kuhn suggested that we "follow the scientific community", Paul Feyerabend suggested we "follow scientific geniuses".
Galileo, Newton and Einstein embodied a rebel spirit that drove scientific innovation.
2 of 5:
Feyerabend saw science as a creative and artistic endeavour and believed that it should not limit itself to one method or constrain itself with dogmatic rules.
It is the people that put their careers and reputations on the line that transforms the history of science.
3 of 5:
If scientists act as self-righteous bullies, treating laymen as idiots, even if they are right, they should expect kick back from the community.
Instead, scientists should aim to broaden the understanding of their work and listen to the concerns of ordinary citizens.
4 of 5:
Competition between different theories, including bad theories, is a good thing. We should not wait for a paradigm change to happen. Scientists should, like Galileo, make a paradigm change happen. It is important for some people to challenge the dominant paradigm.
5 of 5:
Feyerabend does not believe we should elevate crackpot or conspiracy ideas to the same level as scientific orthodoxy, however we should not completely wall ourselves off from the ramblings of mad men, because even the ramblings of mad men could have sage wisdom.

During this pandemic with multiple variants and multiple waves, 10-20% of the population might never be infected. Vaccines are not expected to increase this number by much.
Who ends up in this 10-20% matters.
3 of 4:
The mortality risk to the healthy young is 100,000x lower compared to the healthy old, and 500,000x lower compared to the old and sick.
By closing schools and hiding the young, are we not making it increasingly difficult for the old to remain in the 20% never infected?
This week I am going for my 2nd dose of the Pfizer vax.
The vaccines are completely safe as there is no evidence of long-term adverse effects regardless of how many doses are given. The absence of evidence is the evidence of absence, one of the key principles of EBM.
2 of 7:
Vaccines are thoroughly tested for safety over many years amongst all risk groups.
For example take this Moderna clinical trial amongst pregnant women which will be completed in 2024.
The public can rest assured that the emergency approval of C-19 vaccines will only be upgraded to full approval once all these trials have successfully been completed.
In South Africa, the poor will derive a small benefit from vaccines as immunity levels are already at 60%. The rich will derive a major benefit as immunity levels are low at 20%.
There are no signs of a 3rd wave on the horizon and hospital admissions are the lowest in 10 months and declining. Alcohol restrictions were justified ito hospital demand.
Open air church gatherings pose negligible risks. There should be no cap on indoor meetings. 10 people in a venue for 20 is no different to 1000 in a venue for 2000.
Black Friday was allowed when the 2nd wave was in full swing and casinos never closed.
3 of 4:
Warnings of an imminent 3rd wave when there is nothing on the horizon is irresponsible and results in people avoiding hospitals when they should not.
Now is the time to address the backlog in elective procedures and the neglect of all other health concerns.
