Source criticism in six simple steps
- Who is telling you this?
- How do they know this?
- Do the person have anything to win on you believing this?
- Given #1, #2 och #3, is it possible the person is wrong?
- If the answer to #4 is yes, find another unrelated source
- Repeat until #4 is about as likely as a pink unicorn dancing samba behind your back.
Until the process is finished, assume bullshit
