Fridtjof Nansen

Nansen staked his 1893 Fram expedition on his own unproven theory that sea ice drifts across the North Pole, proceeding despite the Royal Geographical Society's Admiral M'Clintock calling it "the most adventurous programme ever brought under the notice" of the society.

Nansen spent roughly nine years preparing the expedition, working through an iterative ship-design process — "plan after plan," "model after another" — with shipbuilder Colin Archer before departure.

Nine years of iterative preparation before departure is the documented basis for the profile's planning_orientation score. Planning Orientation

During his 1888 crossing of the Greenland ice cap, Nansen deliberately eliminated any option of retreat, later describing the choice as "death — or the west coast of Greenland."

A deliberate, dated decision to remove his own escape options — not merely an absence of caution — is the central instance behind the profile's high risk_tolerance score. Risk Tolerance

Rather than compromise on the Fram's construction quality to control costs, Nansen personally covered funding shortfalls himself, writing that he "did not think it right to study the cost too much."

Nansen's decision to cut off his own retreat during the 1888 Greenland crossing left proceeding forward as the only option — a deliberate elimination of alternatives rather than a contingency plan kept in reserve.
