I am going to say something unpopular.
The vast majority of people do not think. This sounds offensive but let me explain a bit.
Humanity is extremely good at a couple of things. One of them is Mimicry .. in short simple terms monkey see monkey do.
This also applies to thought. We can grab other peoples idea and though patterns for ourselves FAR cheaper And easier then thinking up something on our own. so most people don't think. (the unpopular part)
We Grab Other peoples Ideas And use Them As Our Own. The Good The Bad And The Ugly.
The downside of this is bad ideas perpetuate. Part of this is short term good can equal long term bad. and we all know intelligence isn't equal as much as we would like it to be.
It is an unpopular idea as you said but, there is a side to grabbing people's ideas that are always not visible to the individual doing the grabbing. That's the part where you don't know the plan B or the safety points in the event that a step goes bad.
This is what insures your various moves towards archiving a goal.
Now, not being the originator of that idea puts you steps behind. You might think your ahead due to the fact that, its a continuation from someone else's made up plan but, you don't know how they arrives there.
Every trade personnel has a trade secrete and not knowing that creates some problems.
