Homo sapiens are arguably the most adaptable species on Earth, particularly when you're talking about the ability to fit into a morph an environment to their needs, both ohysicalky and psychologically.

Yet your argument is that change is too scary. Scarier for us than any other species on the planet because we have to have a pyramid to cope? Hmm.

I find your argument lacking. Change is unsettling, certainly. But it doesn't inherently create instability. In at least half the cases, change occurs as a reactive response to maintain or re-establish stability when things have drifted toward extremes. It's a corrective means. All systems need correction from time to time.

If anybody can handle change and instability, it is human beings.

The problem, it seems, is more of an attitude problem than a fear problem. We associate change with negativity and so we resist it.

What it does, is displace contentment, require action or dealing with by trustfalling and the need to rise above our doubts (or, courage).

That's your hard sell. People who are most resistent to change are lazy, cowardly, and like to be kept comfortable because they're low energy, low effort types. They're not the type to see the adventure or potential or have invested in themselves or the world enough to know that if it goes bad, theyll be okay and be able to recover.

Yeah, they'll change if they have to...but the further down this character trait complex one tracks, the more it will take having nothing to lose to change under one's own impulse.
