This chapter is mostly related to evidence in the context of interventions that aim to influence emotions and behavior - despite the fact that most assumptions can probably be applied to a much wider context of evidence of notions and statements in general.
“You can't convince a believer of anything;
for their belief is not based on evidence, it's
based on a deep seated need to
believe.”-Carl Sagan
“(...) If scientific proof was unavailable, the illusion of logic would do.”―Glenn Gould

When someone shows you proof for
"effectiveness" of a method, you should ask
what the intervention was compared to.
Was it compared to placebo, another
intervention - and was it compared at all?
Whenever there is no source of evidence
available for any given intervention, we
should ask Why that is the case.
It is not only interventions that need
evidence, also the many notions and
conceptual assumptions we apply in
everything we do as practitioners.
Facilitating the conversation about
evidence (or lack of the same) is as
important as honesty about existing
evidence.
