If electrical plugs are identical, why do they fit in the outlet only when flipped a certain way?

Plugs with a wider blade and a narrower one are called “polarized” plugs, and they’re designed to make sure you can only put it into a socket one way.
Electricity in the US (most of this applies worldwide, but specifics vary by country) is wired to your outlets with a “hot” wire and a “neutral” wire. For safety reasons the neutral and hot wires must be correctly connected to many pieces of equipment, so a polarized plug is used.
