Men, Women, & Balls

I caught an interesting episode of Freakonomics Radio today, and it got me thinking. It described an experiment by Uri Gneezy of U.C. San Diego. He wanted to explore attitudes to competition in men and women and determine if the differences he has observed are innate to the sexes, or if they are acquired from the culture.  He conducted an experiment that gauged people’s attitude to competition and risk, in two different cultures. The first was the Masai in Tanzania.  This is a very patriarchal society and women are not held in high esteem there.  The second culture was the matriarchal Khasi society of India. In this society women have most of the power and make most of the decisions. Participants in the experiments were tasked with throwing tennis balls into a bucket from a distance. The more balls they got in the bucket, the more money they could win. However each participant could chose from two payment options.  A participant could chose the first option and...

My Amazon Spending

I was buying books online before the web. That sounds impossible, but believe it or not there was a company that allowed you to telnet into its server, search for, and order them. Books have traditionally been expensive in Ireland. Retailers had high margins and books were priced based on IEP/EUR equivalent of UK prices. There is no VAT on books in Ireland so they could be safely imported from the US without additional taxes. I've been looking at my Amazon spend over the past years. My account details in Amazon list pretty much everything I've bought. It's been instructive. The main thing I've learned is that I probably need to buy less and read more. Some of the figures are staggering. In 2007 I spent well over $1000 at Amazon. That was all books. I can't buy DVDs and CDs at Amazon.com. That doesn't include any books I might have bought at other sites like Barnes and Noble. My buying habits have changed. Amazon.com was my long term favorite, but Amazon...

Lies, Damn Lies, Statistics, and Charts

The recent Irish Government report Delivering the Smart Economy provided me with a number of great examples for a class I like to give sometimes about how poorly (often deliberately) designed charts and graphs can be misleading without actually lying. Now I can replace some of my contrived examples with real life ones. The first example Business Expenditure on R&D is unusual. It shows business expenditure on R&D by indigenous and foreign companies over the years. Bizarrely the graph codes the information with bars of three rather colours than two. The far too subtle drop shadow above the bars is meant to point out that the bars are overlaid on top of each other. At a glance it would appear as though the foreign investment is not significantly greater than the indigenous because the total areas of of their respective colours is comparable. A more honest designer would simply have used two colours and stacked them one atop the other. This (the designer might retort) would make ...
