Advent was brightened by a Helsingin Sanomat article on Wikipedia. The reliability of the English Wikipedia has been evaluated several times, but the Finnish version has not been studied in the same way. The Helsingin Sanomat chose 134 articles and gave them to experts for evaluation; there were 96 evaluators from eight Finnish universities. Experts considered, for example, the accuracy and neutrality of the articles on a scale of 1–5. 70% of the articles received a grade of good or excellent in accuracy. According to this evaluation, most articles were written with a neutral point of view, but there were shortcomings with regard to citing sources. Wikipedia writers are often accused of failing to include sources, and readers are accused of uncritical adoption, but these problems are common in other non-fiction as well. After all, people who consult Wikipedia articles have a healthy skepticism, but the same text appearing inside the right covers is considered true beyond doubt. In fact, Wikipedia users are effectively learning critical literacy, because they can see how knowledge is produced. Is it time to improve the Wikipedia articles on your own field? It would be a good Christmas gift for all of us.
