Thanks! (I'm representing the author of the piece) - there's most certainly a lot more depth to how the brain tackles all this chemical activity, but we thought a simplified explanation would be the most useful for people to try and solve the problem.
I'll throw in my two cents on the education side of things. My supervisor is a professor of entrepreneurship. I asked her how she teaches it since she has never started a business herself. She said "When I start the course the first thing I tell them is that most of them are not going to start a business." What she believes is that she teaches them a way of thinking that will help in the future. This was weird to me. Basically, despite "expertise" in the topic, it still boiled down to teaching theory and not how to start a business. But that's just a snapshot of one conversation, take from it what you will.
Generally, there is a division in young graduates: the part that want security and benefits and "not having to think about it" to the idealists who have the potential but are clueless as to how to get started. Divisions between disciplines in the classroom mean that in the past year I've spent more time with anthropologists than engineers. A ridiculous amount of time. Who knows what ideas could have been sparked if I'd hung out after-hours with a few techies instead?
The irony is that many of the top graduates from my class will go on to work for McKinsey and other consultancy companies (it was the top career of choice) somehow deluding themselves that they can offer top advice on something they've never fucking done. Isn't that pretty amazing? I think so. They are not bad or dumb people, but they've been taught that they CAN do it like this.
What other industries can you be a consultant in without prior experience?
