Escape from freedom: Choosing not to choose in pigeons.
Pigeons will dodge free choice when the choice set includes a lousy option.
01Research in Context
What this study did
Researchers let pigeons pick between two paths. One path ended with a choice of two food amounts. The other path ended with no choice — just one fixed amount.
Food totals were the same either way. The only difference was whether the bird had to choose at the end.
What they found
The birds almost always picked the no-choice path. They worked to escape making a choice.
Even though the food payoff was equal, they avoided the link that forced them to decide.
How this fits with other research
Varley et al. (1980) saw the opposite: pigeons fought to reach the free-choice link. The two papers seem to clash.
The gap is in the final options. In 1980 both choices were decent. In 1981 one choice was a tiny, almost worthless pellet. The birds dodged that stingy option by picking the no-choice side.
Azrin et al. (1967) and Cicerone (1976) already showed pigeons care about delay and variability. The 1981 study adds a new lever: when one choice feels bad, animals may pay to skip choosing at all.
Why it matters
Your clients may also 'pay' to escape choice. If a task board offers 'write paragraph' or 'write one word,' some learners will pick the teacher-chosen worksheet to avoid the insulting tiny task. Check whether the choices you give contain an aversive micro-option. Removing that option — or making all choices attractive — can restore willingness to choose and reduce escape behavior.

03Original abstract
Preference for the availability of food-reinforcement alternatives was investigated with Rachlin and Green's (1972) concurrent-chains self-control paradigm. The terminal link of one chain made available a choice between immediate access to food for T seconds and delayed access to food for 4 seconds. The terminal link of the other chain provided only delayed access to food. When T was reduced to .25 seconds, pigeons began to select the delayed-access key in both terminal links. Even so, the pigeons strongly preferred constraint over choice. This effect could not be accounted for by differences in the actual amount of food obtained in the terminal links, by avoidance of the immediate-reinforcement key when not presented as part of a choice, or by avoidance of a multi-key terminal link. Rather, constraint was preferred over freedom. Apparently, the preference for choice is determined by the particular type of choice offered.
