Stephen Dubner, from his Freakonomics blog, points to a study showing my generation to be financially illiterate.
Through my peer-reviewed, purely anecdotal data, this seems to be correct. It's partly because thinking rationally about finance is not intuitive. Even worse, the math involved makes it a hassle for someone trying to compute it correctly.
I remember through my training class for securities licenses, many of us had difficulty with the concepts involved.
If the people who did this for a living had difficulty, what can it be like for the rest of the population?
