Ad ignorantiam ad nauseam
There is a logical fallacy called the argumentum ad ignorantiam or the argument from ignorance. The essence of this fallacy is that because we don't know something to be definitively false, it must therefore be true. A good example relates to concern about the dangers of electromagnetic frequencies.
When diet and exercise aren't enough...
I think this is of the most cruelly deceptive phrases in modern advertising. Firstly, no one wants to change their diet. Secondly, exercise takes time and effort and, at least at first, is quite unpleasant. Taking a pill is ridiculously easy to do. So essentially this advertising phrase applies to everyone with high blood pressure, high cholesterol, metabolic syndrome, adult-onset diabetes or other "lifestyle-related" diseases for which there are profitable pharmaceuticals (or "alternative" treatments, for that matter). It should really be "when diet and exercise don't seem appealing...".
Medicine that Works...
I was at the drug store today to pick up some vitamin D. Living in the dark, cold north requires a bit of extra vitamin D. My levels are particularly low. The label said that any claims on the vitamins had not been evaluated by the FDA for efficacy in the treatment, prevention, or amelioration of any disease. Most of the vitamins on the shelf had doses that were ridiculously high. Being a relatively unregulated market, how does one determine whether the pills will do anything at all or worse, do something bad to you.
No side effects—no effects!
I saw a box of tablets at the coop check-out the other day. The "active ingredient" was at a level less than the equivalent of one molecule in Lake Superior. The box proudly proclaimed: "no side effects!" How amazing! A drug that treats exactly and only the ailment for which it was indicated. This means there is a drug out there that is more effective than the immune system itself. When you have a cold much of the drowsy, low energy feeling you get is due to your immune system combatting the illness. The virus does not cause that feeling itself, your immune system does.
Why do our soldiers have to keep dying for our freedom when the soldiers in other countries that are just as free as us don't? Why should we trust politicians who tell us the soldiers are dying for our freedom when we seem so distrustful of them in all other situations? Shouldn't we be most distrustful of them in matters of war-making?
