I believe the reason for "math phobia" is that there is a greater risk of failure, and that failure can be measured.
We have raised a generation that have high self esteem but can't really produce.
Math has real answers, specific answers. ( well as long as we define the terms) In a base 10 system, 2+2 =4. "3" is a wrong answer'; not worth "partial credit". You just can't BS your way thru math.
However, you can certainly BS your way thru pshychology, or sociology, or even history. And you can feel good about it. I am married to a women who got partial credit on a history exam by answering the question, " What is the Monroe Doctrine" with " It was a doctrine by Monroe"
