Falsifiability
It must be possible to conceive of evidence that would prove the claim false.
Logic
Any argument offered as evidence in support of any claim must be sound.
Comprehensiveness
The evidence offered in support of any claim must be exhaustive -- that is all of the available evidence must be considered.
Honesty
The evidence offered in support of any claim must be evaluated without self-deception.
Replicability
If the evidence for any claim is based upon an experimental result, or if the evidence offered in support of any claim could logically be explained as coincidental, then it is necessary for the evidence to be repeated in subsequent experiments or trials.
Sufficiency
The evidence offered in support of any claim must be adequate to establish the truth of that claim, with these stipulations:
1. the burden of proof for any claim rests on the claimant,
2. extraordinary claims demand extraordinary evidence, and
3. evidence based upon authority and/or testimony is always inadequate.
Conclusion
The first three rules of FiLCHeRS -- falsifiability, logic, and comprehensiveness -- are all logically necessary rules of evidential reasoning. If we are to have confidence in the veracity of any claim whether normal or paranormal, the claim must be prepositionally meaningful, and the evidence offered in support of the claim must be rational and exhaustive.
The last three rules of FiLCHeRS -- honesty, replicability, and sufficiency -- are all pragmatically necessary rules of evidential reasoning. Because human beings are often motivated to rationalize and to lie to themselves, because they are sometimes motivated to lie to others, because they can make mistakes, and because perception and memory are problematic, we must demand that the evidence for any factual claim be evaluated without self-deception, that it be carefully screened for error, fraud, and appropriateness, and that it be substantial and unequivocal.
Being a responsible adult means accepting the fact that almost all knowledge is tentative, and accepting it cheerfully. You may be required to change your belief tomorrow, if the evidence warrants, and you should be willing and able to do so. That, in essence, is what skepticism means: to believe if and only if the evidence warrants.
