There are nine factors that can significantly influence whether one's STEM career will be successful and fulfilling or not. These are the focus of The Brainiac Paradox, but there is much more ... 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: communication. This is the Brainiac Paradox. Communication effectiveness largely determines whether one's work is understood, approved, funded, staffed, supported, and ultimately successful. Communication challenges among STEM professionals result in frustrated careers for those directly affected, and innovation and solution opportunity costs for society as a whole. The Brainiac Paradox tackles this subject head-on, providing relevant information and actionable solutions. Essentially, it is two books in one. The first half addresses the underlying issue, answering the questions of how, why, and so what. It explores various mind sciences research that would seem to suggest congenital explanation. It also reviews environmental development factors that contribute to this phenomenon, if not the outright cause. The second half offers targeted assistance and prescriptive solutions, focusing on the nine factors author Mark Cornillie has found, based his more than 20 years of hands-on experience with this issue, to most impede the success of some STEM professionals. These solutions are provided within the framework of a methodology that will ensure lasting results. But The Brainiac Paradox is not just for STEM professionals seeking greater career success. It also has been written for those who are affected by this issue indirectly: managers, colleagues, loved ones, etc.
