This is missing basic understanding risk management.
Parent is solely focused on probability, when what really matters is outcome.
Lets say that for every 10 years:
1) p of lab leak is 0.002% vs
2) p of nuclear accident is 0.03%
Although (2) is much more probable, from a risk management perspective, (1) is unacceptable because risks compound over time and critically, the domain of outcomes are vastly less localized and certain than (2).
