 Siegler pointed out that Binet was somewhat of an isolationist in that he never traveled outside France and he barely participated in professional organizations.Additionally, his mental scale was not adopted in his own country during his lifetime and therefore was not subjected to the same fate.Finally, when Binet did become aware of the "foreign ideas being grafted on his instrument" he condemned those who with 'brutal pessimism' and 'deplorable verdicts' were promoting the concept of intelligence as a single, unitary construct (White, 2000).
