Numbers never lie.

It has become close to obsession to search the raw data of percentages and such in newspapers. Journalists never know how to interpret data and are unable to calculate even the most simple percentage calculations. You see enormous mistakes in numbers in that very newspaper you have next to your desk right now.

For example, I read a while ago when they were planning to ban smoking in bars in Finland. I calculated all the numbers they gave in the news article and noticed with the data they presented it would mean that yearly about 0,5% of smokers die because of the smoke and 1% of non-smokers. So it's twice as dangerous not to smoke in a bar if other people smoke?

Better to count it yourself.
