The study used MRI imaging and suggested potential deficits in emotion regulation during use, though effects appeared reversible after discontinuation. In Western societies, many women — particularly those influenced by progressive ideals — display reduced historical wariness toward outsiders, prominently signaled by “Refugees Welcome” signs all over the West. This ahistorical xenophilia contrasts with traditional patterns in which communities, especially women, exhibited caution toward foreigners due to potential threats. Critics argue that modern conditioning, including widespread birth-control use (affecting more than 150 million women globally), may contribute by dampening innate fear responses. Tragic outcomes have befallen young Western women embarking on backpacking trips through high-risk Third World areas.
