One way of taking the temperature of society is to go to any news web site and read the comments. This is especially true if you read the comments on the opinion or entertainments or humor columns. A few minutes studying the gems of literary bombast that flow from the (hopefully) inebriated minds of the average web reader will convince you that average IQ is probably a severe exaggeration.
The sad truth is that most of the people writing comments seem to be utterly selfish, hopelessly stupid, incredibly bigoted, abysmally uneducated and irritatingly illogical. If you allow yourself to realize that this is the voting public you suddenly understand why our political system is irreparably broken. These people should never be allowed to vote and preferably never allowed to breed either. Good grief! At least gain enough literacy to be able to tell the difference between news and opinion. Think long enough to understand that news articles are written without all the facts that will ever come out being available. If you waited for all the facts you would still be waiting to read about President Kennedy's assassination. And for the sake of all of us who aren't utterly humor-deprived, develop a sense of humor! When a humor columnist writes about "5 ways to tell your dog is depressed" you can pretty much make bank that it isn't going to be chock full of veterinary advice - key word here "humor" - get it?
What the heck, it's not likely to change soon, but my suggestion is an IQ test before you are allowed to post a comment on a news article. Or better yet, a common sense and normal humor test.
