Sample text

Now, suppose that, on the contrary, I am not certain that I can pass this course. Clearly, this implies that I am lacking in certainty, but what does this mean? I would submit that uncertainty has two quite different connotations, or aspects. On one hand, my uncertainty can arise from doubt. So, the opposite of being sure of passing the course is being extremely doubtful. On the other hand, being uncertain could also mean that I just do not know whether I will be able to pass the course. I may suffer from confusion, because the situation facing me seems ambiguous.

Suddenly, around the year 1890, that all began to change. Like 1654, that year marked a major conceptual breakthrough (this time in the environs of London instead of Paris) and also the birth of the person who would build upon it to create an entirely new conceptual framework for statistics. Actually, the genesis of this breakthrough had been percolating quietly for about 20 years, through the efforts of a remarkable English gent by the name of Francis Galton (1822–1911). By 1890, Galton had fully developed his major statistical innovation.

On the other hand, the actual amount of variability he observed on every characteristic measured was fairly constant across generations. How was this stability possible in a “smart get smarter” world? Galton eventually discovered that this apparent steady state was being maintained by a tendency for the sons of extremely accomplished fathers to “regress” partially toward the overall population mean (average). For example, the son of a genius such as Galton’s cousin Charles Darwin, would also tend to be gifted, but “on average” less so than his father.
