Scientific research is cumulative; many elements of a typical research project would not and could not exist but for the efforts of many previous researchers. This goes not only for knowledge, but also for measurement. In much of the clinical world–and also in many areas of “basic” social and life science research–people routinely save themselves inordinate amounts of work by using behavioral or self-report measures developed and validated by other researchers. Among many researchers who work in fields heavily dependent on self-report instruments (e.g., personality psychology), there appears to be a tacit belief that, once a measure is publicly available–either because it’s reported in full in a journal article, or because all of the items and instructions be found on the web–it’s fair game for use in subsequent research. There’s a time-honored ttradition of asking one’s colleagues if they happen to “have a copy” of the NEO-PI-3, or the Narcissistic Personality Inventory, or the Hamilton Depression Rating Scale. The fact that many such measures are technically published under restrictive copyright licenses, and are often listed for sale at rather exorbitant prices (e.g., you can buy 25 paper copies of the NEO-PI-3 from the publisher for $363 US), does not seem to deter researchers much. The general understanding seems to be that if a measure is publicly available, it’s okay to use it for research purposes. I don’t think most researchers have a well-thought out, internally consistent justification for this behavior; it seems to almost invariably be an article of tacit belief that nothing bad can or should happen to someone who uses a commercially available instrument for a purpose as noble as scientific research. The trouble with tacit beliefs is that, like all beliefs, they can sometimes be wrong–only, because they’re tacit, they’re often not evaluated openly until things go horribly wrong. Continue reading →
