This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

A is for Algorithm
A recipe for a soup or a method of solving long division are both simple examples of algorithms. An algorithm is basically any mathematical method of solving a human problem. More complex algorithms are computer implementable to speed up decision making. Jonathan Everett (Royal Statistical Society) has become concerned about a recent tendency of UK politicians to blame 'mutant algorithms' for poor policy outcomes (https://www.theguardian.com/commentisfree/2021/aug/17/a-levels-pensions-algorithms-easy-targets-blame-mutant-maths). Everett points out that 'mutant algorithms' have been blamed for unfairly allocating 'A' level (pre-University) grades; badly thought out plans for new housing and even the decision to increase UK pensions inline with specific economic indices (the so-called 'triple lock'). The actual choices, however, are made by people in power. They tell the algorithm writer what they want. There's an old computing adage. 'Garbage in; garbage out'. Computing 'errors' are basically down to the operator. There's another, older adage. 'It's a poor workman who blames his tools'. Sloppy thinking seems to underpin the 'mutant algorithms'.
