It’s not really different from paper contracts. Nobody reads them, they just sign where they’re told to.
I've read that contracts fundamentally require a "meeting of the minds", where two parties come to a mutual understanding of an agreement. At the same time, overwhelming people are expected to not read and understand contracts they agree to. I don't understand how these two facts don't combine to mean the vast majority of written contracts are not legally binding, but apparently judges don't share my confusion.
