“If you sell information products, are you responsible for your customers’ results?”
Often people look at this very simplistically and blame the sellers of information products for all kinds of unethical things.
The lack of clarity on what you’re responsible for also makes people accidentally create misleading marketing and unhappy customers, so they’re to blame in part, too.
When you know the things you have to consider, you can make promises in your marketing without worrying about what people might misunderstand.
And at the same time, you can make sure you get almost no refund requests.
