Blogging for the inverterately lazy
Hello, to my now single reader. (I still think it’s my mom…)
Anyway, I’ve obviously not got my act together to blog like Megan McArdle, and as I’m thinking more and more, argue like Don Boudreaux (of whom I am enough of a fanboy to recently buy donboudreauxismyhero.com after seeing some sympatico from Steven Landsburg and [...]
Economic experience in formative years affects adult attitudes
In a paper entitled Depression Babies: Do Macroeconomic Experiences Affect Risk-Taking? (PDF) Ulrike Malmendier and Stefan Nagel try to determine what effect the larger economic environment during childhood has on adult economic decision making. They lead in with the idea that people are biased and will incorporate all available historical data from their experience. From [...]
Stay grumpy and you’ll have a more realistic worldview…
A 2008 paper out of Australia, entitled “Can bad weather improve your memory? An unobtrusive field study of natural mood effects on real-life memory” attempts to show the effects of mood on subjects ability to recall items recently seen in a shop.
Using weather as a proxy for mood, what they found was those who were [...]
Children have innate numeracy
A excellent article from the Economist describes a variety of studies - but primarily one by Brian Butterworth - that show that the ability to count, or more simply, the ability to recognize the number differences in small collections of objects is built in. From Dr. Butterworth’s paper:
Here, using classical methods of developmental psychology, we [...]
Global warming duds…
The Frontier Centre for Public Policy represented an article from the Melbourne Herald Sun entitled Top 10 Dud Global Warming Predictions.
While I would rank myself as a skeptic of global warming, especially of the histrionic man-bear-pig Al Gore variety, articles like this entertain me for reasons other than the debunking.
Global Warming, or Climate Change as [...]
Why you shouldn’t trust forecasts…
…but, you need them anyway. A simple example showing why financial market forecasts aren’t worth much except in terms of historical forensics.
Recently TD Bank suggests that oil prices will be 30USD in the 2nd quarter of 2009.
In their prior forecast they suggested that the price would be closer to 45USD.
In a report on agriculture from [...]
Economic Manhattan Project or simple creative destruction?
In the latest Edge newsletter is an article proposing and discussing an economic Manhattan Project where a group of good scientists would get together and “solve” the current economic crisis. On the surface this doesn’t sound completely bad when the initial description is:
The economic crisis has to be stabilized immediately. This has to be carried [...]
New Toronto trash service offers higher incentive to cheat
In caring, kind Toronto, if you want your garbage picked up, you need to place it in city mandated grey bins or you need to have it labelled with city-issued garbage tags. If neither of these is done, you can’t expect your trash to be collected. Additionally home owners must pay according to the volume [...]
National Geographic is poor with stats
… or at least with their headlines. From an article at National Geographic this week, comes this headline:
Oceans Ten Times More Acidic Than Thought
If this were true then the expected pH of the Ocean at about 8 would probably be acidic enough to eat through most anything. Though exactly what a 10 times increase in [...]
Parents are confused about how to measure children’s weight
A study by Pene Schmidt, released last month, has the plug: 4 In 10 Parents Wrong On Whether Their Child Is Under Or Overweight. While this is an interesting statistic it seems that the study also identified that:
…different methods of assessing children’s weight – such as BMI or waist circumference – result in different rates [...]
