Pandemic of the unvaccinated based on bad science
The Fisman et al. Psi parameter is concocted and invalid

Fisman et al. (2022, 2024) concocted a parameter, which they denote Psi (the Greek letter, ψ). They applied their concocted Psi to incorrectly claim that the risk of infection with COVID-19 to the vaccinated is Psi-fold disproportionately due to the unvaccinated.

Their Psi parameter is mathematically ill-defined, artificially large by its design, and varies in directions contrary to what is physically possible. It is an absurd quantity introduced ad hoc, having no epidemiological basis.

With my co-author Joseph Hickey, PhD, we rigorously proved that the Fisman et al. parameter Psi is nonsense, and we showed that its application can cause harm in society. We made our proof and demonstration in this detailed report:

Incorrect definition and application of a parameter ψ”. CORRELATION Research in the Public Interest, Brief Report, 25 April 2024. https://correlation-canada.org/comment-on-fisman-et-al-2024/ (also available at several other websites)
