Illusions of Lift
A pilot can create an indication of lift on certain uncompensated instruments by entering a climb by pulling back on the stick (hence “stick thermal”). This is not true lift, in that the energy to climb is being converted from decreasing airspeed, rather than being extracted from rising air. Inexperienced pilots can mistake this for actual lift.

“[Humanity] has unquestionably one really effective weapon—laughter. Power, money, persuasion, supplication, persecution—these can lift at a colossal humbug—push it a little—weaken it a little, century by century; but only laughter can blow it to rags and atoms at a blast. Against the assault of laughter nothing can stand.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
