Interpretation: Apply knowledge that you have gained in this chapter and one or more of the FLaReS principles to evaluate the following statements or claims.
An activist claim that if catalytic converters can remove 90% of pollutants from automobile exhausts, it would be easy to remove the other 10%.
Concept Introduction:
FLaReS are a set of rules to test a claim:
Falsifiability: is there any evidence to show that the claim is false.
Logic: Any evidence provided in support of claim must be of sound reasoning. The conclusion follows inevitably from its premises provided the premise is true.
Replicability: If a claim is based on the result of experiments it is necessary for the evidence to be applicable in all the other trials of the experiment.
Sufficiency:
For any claim, the claimant gets the burden of all the evidences. Extraordinary evidences are required for extraordinary claim.
The evidences based on the testimony or authority are not adequate. A claim is said to be true of it possesses all the four sets of rules. If any one of the FLaReS tests is not fulfilled by any claim, it is likely to be false.
