Why throughout history have populations been so easily fired up into supporting extremism, from the deceptive destructive political ideologies of Communism & it's child Nazism, to the much less deadly but horrific cult of ISIS?

"The basic idea that left- and right-wing extremists share a range of psychological similarities is consistent with theories of extremism and radicalisation"

I'd like to see people put hate and conspiracies aside, and transfer energy wasted in contests & conflict into supporting a unique ethically driven project, the launch of the first "Competitive Humanitarian Enterprise Serving Society" as a practical model of bringing people and resources together to drive progress on solving the most complex technical challenges in cancer.

But this paper looks at some of the challenges with primitive, stubborn, human tribalism. all extremists are fixated on simplistic targets of hate/blame

See document Psychological Features of Extreme Political Ideologies.

As an anti-Tribalist this unusual question comes to mind.

Could #FlatEarthers actually hold the key to tackling tribal extremists? "if we can find better approaches to getting #TribalFlatEarthers to look outside their boxes, then perhaps such approaches could be tried with other tribal extremists"

Just as those convinced that the world is flat, or believers in ISIS extremism, some extremists on the Far Left & Right are utterly convinced their simplistic Installed Beliefs are correct and progressive.

For example Believers in cult Marxism have little awareness of what Social Monopolies are, or that failures in regulating monopolies "of all types" are government failures, "not failures of industry" It may be a phenomenally difficult task to explain to those fixed in a simplistic tribal mind-set that actually practically regulating monopolies requires adding competition and overcoming challenges in the practical implementation of that, Not to mention trying to explain their #SimplisticInstalledBeliefs are a product of years of propaganda.
