Deduction

Deduction was a logical process in which an individual or group would gather data to support a line of reasoning, argument or theory. The Doctor utilised deduction on numerous occasions, describing the process of making deductions as "very exciting" in their eleventh incarnation. (TV: The Snowmen) The speed of logical deductions could be measured in gigaflops, at least when performed by a cybernetic being; K9 Mark 2 boasted of being capable of logical deduction "up to within 1.47593 gigaflops".
