Abstract
The effect of birth order on rate of volunteering for a potential group or individual psychological experiment was investigated. Subjects were 286 undergraduates (89 firstborns and 197 later borns). Volunteering was not significantly related to ordinal position. Controls for family size and alternative classification schemes for ordinal position did not indicate any birth order—volunteering relationships. The data were discussed in terms of recent studies which also reported null results.
