First and foremost, enthusiasm: mandate, compliance, jurisdiction. The idea that evidence can 'create' an equivalence is a too-liberal interpretation of mathematical reality and its practical application; evidence establishes an existing relationship, it does not generate it.
The validity of this equivalence relies on strict adherence to the underlying assumptions of the model, which is often difficult to guarantee in real market conditions.
For example, relying on an equivalence proven in the laboratory to assess investment risks in emerging markets with uncertain regulation is a prudence we cannot ignore.
Such abstractions can lead to erroneous capital decisions if the operational framework does not match the premises.
We must always question the scope and limits of theoretical models before integrating them into our investment strategies.
