Uh, no, right hand is acceptance, left hand is simply trying it out for yourself.

Right hand is when mom says "hey don't touch that it's hot, you'll burn yourself!" you say "ok mom, I believe you".

Left hand is when you touch it anyway and learn the hard way why you shouldn't be touching it.

In both cases you know you shouldn't touch the hot thing, but the left hander with his burnt fingers knows very clearly why not to do it.
