How should numeric probabilities be translated into words? Maybe they shouldn't be.
"Words of estimative probability" wreak havoc in high-stakes communication like #intelligenceCommunity assessments and briefings, in part because intelligence and defense institutions map numbers to different words (!) — see Amelia Kahn's forthcoming work at ameliakahn.wordpress.com.
Maths/CogSci/MathPsych lazyweb: Are there any algebras in which you have subtraction but don't have negative values? Pointers appreciated. I am hoping that the abstract maths might shed some light on a problem in cognitive modelling.
The context is that I am interested in formal models of cognitive representations and I want to represent things (e.g. cats), don't believe that we should be able to represent negated things (i.e. I don't think it should be able to represent anti-cats), but it makes sense to subtract representations (e.g. remove the representation of a cat from the representation of a cat and a dog, leaving only the representation of the dog).
We know that the task demands of cognitive tests most scores: if one version of a problem requires more work (e.g., gratuitously verbose or unclear wording, open response rather than multiple choice), people will perform worse.
