I always thought the finance/economics pundits on television weren't much different than political pundits.
In terms of more "serious" economics, at times I wonder why the random walk hypothesis is taken as a premise in various mathematical finance models. (Such as the BlackScholes equation for financial derivatives). That is, besides mathematical convenience and solvability.
