Tough call.
Probably more bad than good.

The Belcerebons used to cause great resentment amongst neighbouring races by being one of the most enlightened, accomplished and, above all, quiet civilisations in the Galaxy. As a punishment for this behaviour, which was held to be offensively self-righteous and provocative, a Galactic tribunal inflicted on them that most cruel of all social diseases: telepathy.

Much worse: there are barriers to protect us because the majority would not be able to handle it- instead of instant empathy, I would bet on hostility and other not so healthy coping mechanisms. Dilly dilly!

If it happened suddenly, I have no doubt it would cause chaos and hatred. It would be awful. I mean seriously, when I think of my innermost thoughts being out there, it scares the crap out of me.

That would be horrible. Sometimes my thoughts scare me. We would all have fewer friends if any at all. Marriages would last a week maybe two if you could really control your thoughts. Bad, bad idea.

I think it would be terrible. I would probably get fired from my job.

Worse off, there would be far too much.... Punishment for Thought Crimes....Now where have I heard that before?

Mmmmmm not sure....

Better, but the learning curve would be REALLY ugly.
