Anybody who installs or replaces electrical outlets needs a polarity tester. They will tell you if an outlet is wired backwards and will test GFCIs. Most houses will have one or two outlets wired wrong. I once found a GFCI outlet that had THREE different wiring errors: backwards polarity, load and line reversed and a bad ground. Note that the polarity tester will find most, but not all, wiring errors.
As others have said, there's a very good chance the light switch you want to add an outlet to doesn't have both hot and cold conductors. The older the house, the more likely this is. Or if the switch happens to be a three-way. Personally, I don't care to have receptacles and switches in the same box; if it was me I'd probably install a second box exactly where I want it. Or get my electrician son to do it for me.
Wiring is polarized for safety, to reduce the likelihood of electrocution. I don't know of any device that will be damaged if its AC polarity is reversed. Given the number of outlets wired with reverse polarity, things would be blowing up every day if this were true.
