Counterfactuals are not causality
Notice in the incident analysis I outlined earlier, there are three counterfactuals listed. Counterfactuals are the condensation nuclei for blamestorms. As long as we remain clear that these counterfactuals are not the cause of the problem that already happened, but are changes to our reality that can prevent future occurrences, we can use them without inducing blamestorming. Sometimes we even go further steps away from reality by postulating still more counterfactuals that could compensate for the negative consequences of the first one. Counterfactuals don't say anything about what actually happened. Try to reformulate counterfactuals offered as explanations for past events so you can state them as injections to prevent recurrence. Watch out for the pitfall of counterfactuals when analyzing anything.
