There is no accusation of conspiracy. Rather, this is an account of embedded thinking. The author references Aristotle, to illustrate that it has always been this way. Aristotle’s approach to ethics was observational, and the world around him was one of manual labour and subjugation of women. Hysteria is from the Greek root hystera, meaning uterus, and only women could become hysterical. This book is not a recycled or superficial condemnation of etymology; it sets out to foster an appreciation of how easily bias slips into our thoughts and assumptions.
Objective reasoning is challenged by unconscious and subjective perceptions. Problem solving for new products, therefore, can often overlook women. Many of the examples in the book are down to people simply not having thought of something.
We can be blind to the obvious, and we are also blind to our blindness. Daniel Kahneman
