[The lifespans of scholars referred to different disciplines according to data from diverse sources: Inferences and challenges.]

ABSTRACT

Human lifespan is known to correlate positively with education level. In the present paper, it is explored whether there are significant differences in lifespan among those whose education may be reasonably rated as the highest possible, i.e. among scholars referred to different scientific disciplines. The publications where the lifespans of scholars were estimated against the general population are reviewed, and the estimates are compared with those derived from the Database of Persons Included in Encyclopedias (DBPE), which has been being developed by the authors since 2008 based on Wikipedia records. With all caveats associated with the peculiarities of the procedures of including biographic data in Wikipedia, the estimates derived from the latest version of DBPE correspond to earlier estimates and confirm the conclusions based on other data sources scholars' mean age at death (MAD) and life expectancy (LE) steadily increased since the Medieval period up to the modern time, were higher than those of the general population, and where the highest among the scientific elite. An unexpected finding was that MAD and LE of economists were usually the highest, whereas those of the mathematicians were lowest compared with specialists in other research fields. The difference between the two extreme cases ranges from ca. 3 to 5 years in different historical periods. Further examination of the difference between the extremes may reveal what factors behind it may be at work generally, even though they manifest themselves less overtly in other cases.
