Scientists, Technologists, Engineers, and Mathematicians (STEM) are widely accepted to be among society's most intelligent people, and yet some struggle with something those on the other end of the cognitive spectrum may handle with ease: connecting with other people. It's a paradox...the Brainiac Paradox. Communication and collaboration effectiveness largely determines whether one's work is understood, approved, funded, staffed, supported, and ultimately successful. But the Brainiac Paradox hinders these, denying society valuable advancements and some STEM professionals career fulfillment. For more than two decades, Mark Cornillie has tackled this issue at some of the largest organizations in the United States. In The Brainiac Paradox, he shares special insights to this phenomenon and practical, prescriptive, and proven solutions that will help: Technologists, engineers, and mathematicians who struggle professionally, not because of the quality of their work, but due to aspects of their interpersonal interactions. Managers and HR professionals who grapple with what to do with high-potential STEM professionals whose work is hampered by communication or collaboration issues. Colleagues, project managers, and others whose work is affected when technical professionals do not interact effectively. Loved ones and friends of affected individuals, disheartened to witness once promising careers evolve into sources of frustration and pain. Educators and mentors guiding the next generation of technologists. Brainiacs in all forms - from the neighborhood teenager who configures computers to the Nobel Prize winning physicist - are precious resources in this age. Yet, even as industry, government, and academia plead for more young people to enter STEM fields, they overlook untapped potential among their current ranks. Finally, there is a way to unlock that potential: The Brainiac Paradox.
