Well, if you want to get technical, the IQ in the expression "I'm talking about actually raising IQ" means the underlying general intelligence factor g which is unobservable directly. The results of IQ tests are estimates of that underlying factor g and for different IQ tests these estimates might be pretty good, pretty bad, biased, etc. In particular, if a particular IQ test looks strange to you, its estimate of your g is likely to be biased downwards and, vice versa, if you prepared very diligently for a specific test, its estimate is probably biased upwards.
