Hi WP: Fear is our most powerful emotion, above even love. Marketing experts use subtle fear to sell products. To the extent that most do this, they remain reasonably ethical ... much of the time. Religions vary much more. The JWs, as a religion that markets itself, uses fear to the limits.
It is fun to sit back and watch TV ads or listen to radio ads use fear, mostly fear of loss ... "If you don't use Our Breath Mint, then the girl will not want to kiss you." If you "Don't buy Our SUV, and you won't have as much fun in the country." if you "Don't use our Pill, then you will suffer longer."
I especially love the way Pharmasuitical companies have to disclose side effects. "Take our Pill to cure you depression, but you may end up vomiting, getting the runs, loss of hair, impaired vision, loss of concentration, or death. If you take other medications, be sure to concult with your doctor as there may be serious drug interactions, such as erectile dysfunction, loss of interest in sex, high blood pressure, and stroke."
True, the Physicians Desk Reference reports that the chance of side effects are minimal and often only occur in laboratory rats. But, they are forced by law to disclose anyway ... so, the mixed fear signals to use their Pill or not to use their Pill is very fascinating.
Good points on fear ... yes, I agree 100%.
