Misleading experimental findings may emerge because experimenters fail to eliminate the effects of achievement motivation. It is suggested that few experimenters control for these effects because no convenient measure is available. The construction of a 10‐item scale of achievement motivation and a seven‐item ‘carelessness’ scale is reported. The scale's validity is assessed from correlations with McClelland's test and from correlations with other variables. In addition, the scale is shown to discriminate between a panel of volunteers and a sample of men drawn from Who's Who. The scale could also discriminate between subgroups in the Who's Who sample. The split‐half reliability of the measure is reported.
