The most common mistake people make is to subject persons with sensitivities to a reverse onus when they report their experience of repeatable, controllable circumstances, contrary to ethics, social convention and laws since the Magna Carta. This practice is unethical in any context, but becomes especially damaging in clinical medicine.
"An important point is the fear of liability (at the legal and moral level) which perpetrates attitudes and actions. The protective psychological mechanism that comes into action when one knows deeply other people have been harmed, because of their negligence, or because they have been hiding behind the presumed lack of science, because they have minimized, belittled the issues, this mechanism which hides behind denial, camouflage, or aggression needs to be uncovered. Consequences need to be brought to the conscious level, for healing to take place, and prevention to take its role.
“We examined the prevalence of multiple chemical sensitivities (MCS), a hypersensitivity to common chemical substances. We used a randomly selected sample of 1582 respondents from the Atlanta, Ga, standard metropolitan statistical area.

Some politicians will quite casually lie in ways that cause thousands of deaths. Most will turn a blind eye to damaging statements from their party if doing otherwise means acknowledging previous liability. When told of harm caused by their colleagues, politicians such as Paul Dewar launch into an ad hominem defence, diverting attention while vulnerable persons continue to be needlessly killed.
Agencies of remedy exploit peoples' terror, telling persons with diagnosed sensitivities that they will be shunned unless they they help cover up agency mistakes that are contributing to the ongoing killing of persons with undiagnosed sensitivities.
Researchers at the University of Toronto accepted money and pretended that things already known were not known. They accepted money to research things they knew or ought to have known were impossibly defined. They allow the damaging misinterpretation of their work by funders.
