- [FROM: Dennis Delprato (930106)]
-
- Those who work with psychological and social data and
- take a strict anti-statistical stance might find of
- interest an article entitled "How Hard is Hard Science,
- How Soft Is Soft Science?" authored by L. V. Hedges
- (American Psychologist, 1987, v. 42, 443-455).
-
- Hedges notes striking parallels between quantitative
- methods used to sythesize research in the physical and
- in the social sciences. He found that the most common
- method used in the physical sciences makes use of weighted
- least squares, and notes that this procedure is now
- used in the social sciences (and I would add bio-medical
- sciences), as well. Hedges takes as examples the Particle
- Group Data reviews that examine "stable-particles" and
- focuses on mass and lifetime estimates. He argues that
- the Birge ratio (the accepted index of determining "how
- well the data from [a] set of studies agree (except for
- sampling error)" is comparable to that obtained with
- socio-behavioral research.
-
- Hedges recognizes that he did not examine research
- concerned with testing point predictions.
-
- My point here is that anti-statistical positions such
- as taken by operant psychologists and PCT experts might
- appear naive from the perspective of science as a whole
- unless they are qualified.
