A claim is a belief that is put into words. It is a statement that someone claims to be true. But it might be false. How do we determine the truth of a claim?
Some claims are pretty obvious:
- The World Wide Web contains billions of pages.
- The word "claim" is spelled with five letters.
Some claims can be validated by eyewitness testimony:
- He was stumbling and slurring his words.
Verifying some claims requires expertise and systematic study:
- In developing nations, as the social and economic status of women improves, the birth rate falls.
Most claims are based on data--facts that we observe about the world.
- Some data are easy to gather.
- Other data may take funding and special skills to acquire.
Data require analysis and interpretation before we can make conclusions.
- For "everyday" data, this isn't a problem for us.
- But sometimes it requires training and experience.
How do you evaluate the truth of a claim when you lack the data and specialized interpretive skills?
- Answer: You evaluate the source of the claim. If it is credible, then you can accept the claim as (probably) true.
However, before you scrutinize the source of the claim, examine the claim itself.
