superstitious Pigeons & humans
To say that a reinforcement is contingent upon a response may mean nothing more than that it follows the response. It may follow because of some mechanical connection or because of the mediation of another organism; but conditioning takes place presumably because of the temporal relation only, expressed in terms of the order and proximity of response and reinforcement. Whenever we present a state of affairs which is known to be reinforcing at a given drive, we must suppose that conditioning takes place, even though we have paid no attention to the behavior of the organism in making the presentation. A simple experiment demonstrates this to be the case.
A pigeon is brought to a stable state of hunger by reducing it to 75 percent of its weight when well fed. It is put into an experimental cage for a few minutes each day. A food hopper attached to the cage may be swung into place so that the pigeon can eat from it. A solenoid and a timing relay hold the hopper in place for five sec. at each reinforcement.
If a clock is now arranged to present the food hopper at regular intervals with no reference whatsoever to the bird's behavior, operant conditioning usually takes place. In six out of eight cases the resulting responses were so clearly defined that two observers could agree perfectly in counting instances. One bird was conditioned to turn counter-clockwise about the cage, making two or three turns between reinforcements. Another repeatedly thrust its head into one of the upper corners of the cage. A third developed a 'tossing' response, as if placing its head beneath an invisible bar and lifting it repeatedly. Two birds developed a pendulum motion of the head and body, in which the head was extended forward and swung from right to left with a sharp movement followed by a somewhat slower return. The body generally followed the movement and a few steps might be taken when it was extensive. Another bird was conditioned to make incomplete pecking or brushing movements directed toward but not touching the floor. None of these responses appeared in any noticeable strength during adaptation to the cage or until the food hopper was periodically presented. In the remaining two cases, conditioned responses were not clearly marked.
The conditioning process is usually obvious. The bird happens to be executing some response as the hopper appears; as a result it tends to repeat this response. If the interval before the next presentation is not so great that extinction takes place, a second 'contingency' is probable. This strengthens the response still further and subsequent reinforcement becomes more probable. It is true that some responses go unreinforced and [p. 169] some reinforcements appear when the response has not just been made, but the net result is the development of a considerable state of strength.

This is from a Skinner paper in the late 40's. Behaviour can conditioned by a stimulus even when the behaviour itself has no effect on outcome. So, we have pigeons repetitively tossing and turning with the superstitious 'belief' that this caused the rewarding outcome.
So, are humans so easily led in their beliefs/superstitions, behaviour and causal explanations? We would think so...
Everyday Magical Powers: The Role of Apparent Mental Causation in the Overestimation of Personal Influence
These studies examined whether having thoughts related to an event before it occurs leads people to infer that they caused the event”even when such causation might otherwise seem magical. In Study 1, people perceived that they had harmed another person via a voodoo hex. These perceptions were more likely among those who had first been induced to harbor evil thoughts about their victim. In Study 2, spectators of a peer’s basketball-shooting performance were more likely to perceive that they had influenced his success if they had first generated positive visualizations consistent with that success. Observers privy to those spectators’ visualizations made similar attributions about the spectators’ influence. Finally, additional studies suggested that these results occur even when the thought-about outcome is viewed as unwanted by the thinker and even in field settings where the relevant outcome is occurring as part of a live athletic competition.
Pronin et al., (2006).
We could very tentatively extrapolate this to early humans performing behaviours to invoke good outcomes from an external effects (rain dances etc). And they may even go further and invoke a cause beyond the norm, i.e. things happen beyond their control, the people see patterns and effects, but no explainable cause, most cause & effect relationships would be seen to the result of an agency. We invent a cause agent to fill the hole - gods/godesses/animal spirits. We start to perform rituals to improve outcomes (please agent), some become associated via conditioning-like effects to a rewarding stimulus. So it's normal for animals to associate behaviours with outcomes and attempt to make causal connections, often erroneously.
It seems to make sense to me, but then again, I haven't slept tonight, so don't be too hard on my insomniac ramblings, haha.
