Should we lower IQ in exchange for better looking teeth?

>>9071169
I'm not sure what you're suggesting.

>>9071169
You better have some proof that it lowers IQ. An easy piece of evidence would be to list the IQ statistics of the countries in your graph.

>>9071169
>toothdecay listed
>england not on chart
>too high

>>9071169
Nothing in that chart is indicative of a correlation between water fluoridation and IQ. Does go to show that fluoridation x dental condition is also insignificant.

This, fluoridation should be stopped simply because it's clearly not having the intended effect

>>9071169
look like only anglo country fluoride their water.
Can other non-anglo country confirm this?

>Does go to show that fluoridation x dental condition is also insignificant.
There's no control for natural fluoridation and dental fluoridation, so it doesn't show that. The only thing it shows is that tooth decay has dropped to the same levels in those countries.

>>9071327
you cant infer the effect of fluoridation just by looking at that chart.

>>9071169
We should ditch the processed foods with lots of sugar instead

Rich people in america filter their water. If you don't know this its because you are poor or nouveau riche

If the content of sugar in foods has gone up shouldn't the number of cavities have also gone up?

Yes, the same way we should be improving our infrastructure by eating more mozzarella cheese.

I don't think you understand what insignificant means.

That line isn't as steep

Only if you don't count the population growth of africa.

That world IQ graph has no source and comes from a British tabloid site.

WHAT HAS NASA BEEN UP TO

>>9074843
it is a scientific fact that many poor countries where children do not eat fish and vegetables in their early years have underdeveloped brains (and thus, lower iq).
