7/27/07 The Dunning-Kruger Effect

Today I learned about the Dunning-Kruger Effect. It's something we've all seen. "The Dunning-Kruger effect is the phenomenon wherein people who have little knowledge think that they know more than others who have much more knowledge."

From the "Just buy a Brita" files: The water from both Aquafina (Pepsi) and Desani (Coca Cola) come from a public source. In other words, they're purifying tap water and bottling it.

I was watching another episode of "The Universe". This week's episode was about Saturn. Saturn has something like 48 known moons. The biggest and most talked about it Titan. What's interesting about Titan is that is has an atmosphere. The atmosphere consists mainly of nitrogen and methane - Which is similar to earth's early atmosphere. Since it's so cold on Titan, methane is in a liquid form. Here's the part I found cool - It rains methane and there are methane rivers.

I have always made the comment that "Bottled at the source" could mean anything. People would ask me what do you mean? I would take an empty bottle and put it under the tap and say, "Lokk, I am bottling water at the source!" They would say I was being dumb...guess I was right all along!

Assuming that Aquafina and Dasani use more than carbon filters to process the water, are they not adding value?
