Statistics

The parable of the streetlight. Do you know the one about the drunk looking for his keys under the streetlight? That's what I think of statistics and scorecards. Is it better to look where it's easy to see lots of information with the slight chance of discovering answers, or is it better to search in unknown areas which are more mysterious and risky and more likely to deliver answers? Just because you calculated an answer based on easily-accessed data that's been interpreted and passed through an organizational filter, doesn't mean the answer is accurate.

Not everything can be analyzed with numbers. Yes, it is true that numbers don't lie but it is also true that numbers are used to justify or produce lies. Be careful.
