It's not a very powerful setup. They had 30 people in each group and 6 dropped out of two groups.

To see how lousy it is, consider that "Delay-discounting task delay" Was lowered in the control group from 0.76 before the study to 0.03 at the end of the study while the GTA group saw their level rise from 5.22 to 25.34 (see Table 1). The conclusion their methodology came to was that there was no difference between the two groups (p=0.26).

So, the authors conclude 0.03 is about equal to 25.34.

if you're seeing differences that large and concluding there is no difference the design makes it junk science. The conclusion was a result of the design.

That doesn't mean that these games cause problems, only that this study isn't very informative.

Uh, you might want to google a term before you use it. try wikipedia for a definition of commodity currency, "A commodity currency is a name given to currencies of countries which depend heavily on the export of certain raw materials for income."

My point is that gold has value because people agree it has value, not because of anything intrinsic in gold. Basically, without the agreement that gold has value it would have a value higher than copper. Silver is even more so, I doubt it would rise much past the price of copper.

You got me there.

Yeah, remember how that Democratic president declared war on Hitler and then mopped the floor with him? When's the last time a Republican actually won a War? 1865?

ding ding ding! Gold is also a fiat currency.

Yeah, those are nasty too

Nevertheless, it's a good point. I mean, one is syphoning money out of someone else's pocket and the other is making the planet warmer, with unknown consequences. But they both cost others.

Might have been before, but now electrics are getting CO2 emissions similar to 50-150 MGP cars, depending on your local electric company's mix.

The radiation is mostly cosmic and, if you've ever priced a chip that is hardened for space travel, you'll know it isn't a minor price difference. It's nasty.

Change D to R and you've basically got Fox News and Rush talking points, which are basically marching orders for the Rs.

Wow, the Russian AC crowd is out in force here.

Yikes, a phone book would cost millions!

Thinking while on slashdot has gone from optional to rare.

No need to be fair. Just consensual. Sometimes the free market gives you a good that the seller knows is worthless. Free marketers have to say that there is a correction that prevents or surpasses this, or acknowledge that it's just a cost of the free market.

Has this happened in the last 100 years in the US?
