Spearman's Law of Diminishing Returns (SLODR) with regard to age was tested in two different databases from the National Longitudinal Survey of Youth. The first database consisted of 6,980 boys and girls aged 12–16 from the 1997 cohort ( NLSY 1997 ). The subjects were tested with a computer-administered adaptive format (CAT) of the Armed Services Vocational Aptitude Battery (ASVAB) consisting of 12 subtests. The second database consisted of 11,448 male and female subjects aged 15–24 from the 1979 cohort ( NLSY 1979 ). These subjects were tested with the older 10-subtest version of the ASVAB. The hypothesis was tested by dividing the sample into Young and Old age groups while keeping IQ fairly constant by a method similar to the one developed and employed by Deary et al. (1996) . The different age groups were subsequently factor-analyzed separately. The eigenvalue of the first principal component (PC1) and the first principal axis factor (PAF1), and the average intercorrelation of the subtests were used as estimates of the g saturation and compared across groups. There were no significant differences in the g saturation across age groups for any of the two samples, thereby pointing to no support for this aspect of Spearman's “Law of Diminishing Returns.”

Diminishing Returns

This chapter investigates whether the growing enthusiasm for ecosystem services recently expressed by conservation NGOs and international institutions is supported by evidence. Ecosystem services—the benefits humans receive from nature—have become the darlings of conservation on the assumption that the valuation of selected services may justify protecting land. A critical examination of a random sample of monetary valuations for regulating ecosystem services such as pollution treatment, finds that only onethird can be considered reliable, and that only ten percent of monetary value estimates can be transferred to other contexts. This suggests that the overall evidence base for assigning monetary value to nature is limited. Furthermore, diminishing returns, high opportunity costs, and technological substitutes might limit the amount of conservation that can be justified on the basis financial assessments of ecosystem services. As such, this chapter concludes that ecosystem services as a conservation strategy should not be embraced uncritically.
