Non-religious human sheep are defined (by me) as those who accept whatever they read or here without checking. If corralled and interviewed they parrot whatever they have picked up and treat it with the same status as anything they'd studied for an exam, although it turns out they only have a general set of cliches available and little or no data to support it. That attitude is a pre-academic one, and although academics are not immune to it occasionally it seems the default among people who have not been trained to check their information before treating it as accurate and passing it on to fellow sheep.
As unfortunately they clearly make up the majority of the population the goats (the leaders in the know) exploit this attribute and can easily make things up to persuade people to buy their products, hate their enemies and the like when in fact people taking 125% mortgages, adding to their credit limit and buying structured financial instruments are all things the bankers themselves would rarely if ever do but the sheep do en masse. Most bankers would not touch a credit card with a barge pole. That demonstrates the perfect example, those who are in charge do not do what they persuade others to as they know it is wrong. And credit cards are just the best of pages of similar examples, I'm sure we can all think of many more.
