This sort of behavior — called 'bistability' — is familiar to anyone who has operated an old-fashion 'snap-action' light switch (as explained, for example, in Wikipedia), which toggles abruptly between lights on and lights off as the lever is pushed beyond the central position.
Thus, my action of flipping the light switch can be explained by reference to my having the belief that flipping the switch turns on the light in combination with my having the desire to turn on the light (for most explanations explicit reference to both the belief and the desire is unnecessary).
Thus my action of flipping the light switch can be redescribed as the act of turning on the light (under which it is intentional) and also as the act of alerting the prowler who, unbeknown to me, is lurking in the bushes outside (under which it is unintentional).
In the first case, the action of reaching for the light switch is thought to be guided by implicit control, which is abstract and unavailable to consciousness [1], [2], [3], [4], and which is typically engaged in "automatic" movements, such as steering a car.
"You can see the butterfly effect of your actions, so they will think, 'Oh, polar bears drowning connects to my light switch.'".
