Bloom has defended the forced-choice form of the Machiavellianism scale from observations by Ray that such scales have intrinsic validity problems--particularly with social desirability. Bloom also has shown that the failure of the F scale to predict authoritarian behavior does not necessarily deprive it of all claims to validity. It is pointed out that Bloom's observations contain nothing new and ignore important considerations. The validity problems of forced-choice format are elaborated by means of examples, and it is pointed out that Bloom appears to lack criteria for ever allowing the F scale to be shown as invalid.
布卢姆为马基雅维利主义量表的强制选择形式进行了辩护，回应了雷的观点，即此类量表存在内在效度问题——尤其是在社会期望性方面。布卢姆还表明，F量表未能预测独裁行为并不一定意味着它完全没有效度可言。有人指出，布卢姆的观点并无新意，且忽略了重要的考量因素。文中通过实例阐述了强制选择形式的效度问题，并指出布卢姆似乎缺乏判定F量表无效的标准。
