FAQ
Frequently Asked Questions
Yes, but it functions almost exclusively as a proper noun referencing a specific historical case study, not as a general vocabulary item.
No. It is an extremely obscure historical reference. Using it would confuse almost all listeners outside a very specific academic field.
You must acknowledge its origin in the pseudoscientific eugenics movement and its use in stigmatising people with disabilities. Using it neutrally is misleading.
No, as a proper family name, it is typically not pluralised (e.g., 'the Kallikaks' would be unconventional). The plural reference is usually 'the Kallikak family'.
