What are some examples of 'common sense' which are nonsense? (lemmy.ml)

Wikipedia defines common sense as "knowledge, judgement, and taste which is more or less universal and which is held more or less without reflection or argument"

Try to avoid using this topic to express niche or unpopular opinions (they're a dime a dozen) but instead consider provable intuitive facts.

Not entirely true. Vaccines induce the adaptive immune system, which is slow but precise. Getting sick for real induces the innate immune system, which is god awful and you should not be relying on it. S. pneumoniae causes pneumonia because the innate immune system goes overdrive and kills you before it kills the bacteria. COVID-19 induces cell-innate inflammasome activation and leads to a cytokine storm, which then leads to even more damage to the lungs as the immune cells come in. Both diseases have effective vaccines that do not do anything close to this.

Deadly diseases tend to be deadly not because of the microbe itself, but because the innate immune system overreacts and kills you in the process of fighting off the disease.

Getting vaccinated diminishes the role that the innate immune system plays when you get sick, since the B cells responsible for producing antibodies for the disease are already mature. Having available antibodies also allows the immune system to rely on the complement system, which allows it to detect and kill invading microbes way earlier than otherwise.
