4 Stephen Jay Gould Quotes on Data

Stephen Jay Gould quotes on data

30. Thus, we have three principles for increasing adequacy of data: if you must work with a single object, look for imperfections that record historical descent; if several objects are available, try to render them as stages of a single historical process; if processes can be directly observed, sum up their effects through time. One may discuss these principles directly or recognize the 'little problems' that Darwin used to exemplify them: orchids, coral reefs, and worms-the middle book, the first, and the last.

75. All interesting issues in natural history are questions of relative frequency, not single examples. Everything happens once amidst the richness of nature. But when an unanticipated phenomenon occurs again and again-finally turning into an expectation-then theories are overturned.

193. He confronts a basic tool of the measurers-the statistical technique called factor analysis, developed by the influential English psychologist Charles Spearman-and demonstrates persuasively how factor analysis led to the cardinal error in reasoning of confusing correlation with cause, or, to put it another way, of attributing false concreteness to the abstract.

He stops at each point to illustrate both the logical inconsistencies of the theories and the prejudicially motivated, albeit unintentional, misuse of data in each case.: A major addition to the scientific literature.
