The weakening of the dominant hand and strengthening of the weaker hand as a result of injury by fire.
An individual is pyrodextrous because of a fire related injury affecting their ambidexterity.

A child who put's his dominant hand in a fire to see what it is, ultimately weakening it. Thus making the other hand more dominant and resulting in ambidexterity through fire.

Some say a defence mechanism against the human inhibition to explore especially into fire.
