I totally agree. Kids just don't have the work ethic.
I disagree. It's the teachers that don't haev the work ethic, or the knowledge.
I've met two teachers in my life who have known what they're talking about. The rest of them were way too easy, had no idea what they were talking about, and wasted most of my and my peers time.
Really, it's a combination of both. Most of the fault lies in the parents however, for not taking responsibility to make add the work ethic to their kids and also fault in the school districts for hiring crappy teachers.
My geometry teacher last year was a basically stoner. He mumbled a lot, forgot what he was saying, looks at people playing pianos on youtube all day/ on the comp all the time, and he never checked the homework. I once turned in a blank piece of paper and a sudoku puzzle in and got full credit.
I also have this PE teacher who looks at porn on his I-phone. BTW he has two daughters and a wife. >_<
One HUMONGUS reason more and more children are dumb, like lieutenut said is because the parents do not dicipline their children, nor give them chores they just let them sit on their butts playing video games and watching TV
My parents are extremely lenient about discipline, and I haven't turned out worse for it whatsoever. A lot of it comes down to the psychological profile of the kid.
The problem with the site you linked was that it didn't actually menhtion how the data was gathered. However, I'd like to reiterate that intelligence doesn't just exist in a vaccum. You have to take into account massive population growth in 3rd world countries as they experience their industrial age. So yes, on average they may be bringing the global mean down. That is not to say people are getting less intelligent, just that there are more people to skew the results.
Determining intelligence via an IQ test is like ascertaning someone's athletic ability by seeing how many chin ups they can do. Some are very good at them, but are not the best athletes, whilst some very good athletes can't do chin ups. Sure it averages out as a pretty good guide, but at the individual level it has a large margin of error, which is what most people don't realise. To find out one's true intelligence it would require grading them objectively and comprehensively in every intellectual aspect of life, which is indeed impossible even in theory, because we can not know what the other is thinking.
