When cooking with tinfoil, why do you put it with the shiny side towards the food?

If we cooked food by shining bright lights on it, it would make sense to put the light-absorbent side out — but we don't (usually) cook food that way. If we cooked food until it became glowing hot, it would make sense to put the reflective side in — but we don't do that either.
In fact, I was under the impression that most cooking techniques worked by conduction or convection, not radiation. So why do the reflective properties of the foil matter at all?
