If there's traffic, he's always late.
Hmm. I suppose the main clause in every 'cause and effect' IF statement can be re-presented as a conclusion; but I'm not sure that every 'epistemic' IF embodies a cause and effect:

1. If there's a lot of traffic, he's always late => he's late, so I conclude that there's a lot of traffic.

(Which may be invalid.)

2. If it's dark outside, it isn't noon => ?It isn't noon, so it's dark outside.

(Which is invalid.)

I suppose in such cases we're always at risk of 'affirming the antecedent':
If P, then Q.

Q, therefore P.
MrP (or Q)
