Cognitive Dissonance in history,
Two Midwest mechanics shed the university bound determinations that heavier than air controlled flight was impossible and not practical in 1900. The cognitive dissonance that flying cannot be done was garbage product of the best, most prestigious universities around the world and all the rest of educated societies from coast to coast and over the oceans. Pilcher and Lilienthal died attempting to fly gliders and still some knew it was possible and attempted the feat.
The successful brothers tried first the best advances of science in their designs. Their high school math didn’t let them down, the assumptions of coefficient values of science were wrong. Consider for a moment so called bicycle mechanics educated no farther than public schools had the physics and trig down as only high school grads with the self education of interests in racing bicycles and selling bicycles. Now compare that to the education today of high school grads IF parents leave the education to the slime-on-the-video and schools.
The Wright Brothers shed the cognitive dissonance when they learned the science was wrong by hands on experimentation. Home in Dayton they built a world class wind tunnel and test apparatus from scrap spokes and hack saw blades. An aeronautical lab to rewrite the bad science and do their own critical thinking. They established the real coefficient of lift and drag for their machines and redesigned a new one using that data.
In that choice the die was cast and the first human controlled powered flight of a heavier than air craft was only a matter of time. Shedding the false science and exercising critical thinking the impossible was accomplished. And further refined outside Dayton to practicality.
It took five years before the world accepted the reality of the Wrights flying machines, but it had to admit the truth before the World War of 1914.
Critical Thinking and refusal to participate in cognitive dissonance can force the world to change.
