About the book

We live in a world where proven facts, verifiable data, and actual truths are freely and widely available.

So why are self-confident ignoramuses so often believed?

Why are thoughtful experts so often given the cold shoulder?

And why do some people seem credible yet others inherently untrustworthy - even when they're saying the same thing?

In this ground-breaking new book Stephen Martin and Joseph Marks identify the powerful, hidden forces that result in some people becoming society's prevailing Messengers while others end up woefully ineffectual or under-represented.
