Matthew Lieberman, an American psychologist and professor, has been studying social pain for over thirty years, linking it to loneliness and lack of social skills. His work has gained significant recognition, especially after the COVID-19 pandemic, which has emphasized the impact of social isolation on mental and physical health. Lieberman's theories suggest that loneliness can cause pain comparable to physical ailments, a notion that was once dismissed by many in the psychological community.

With more than 58,000 academic citations, Lieberman's insights are coming to the forefront as society grapples with a growing loneliness epidemic. His book, "Social," reveals how social connections are fundamental to our well-being and how their absence can lead to serious health issues. The publication of the Spanish edition now plays into a wider context where the relevance of these discussions is critical amidst rising loneliness post-pandemic.

Lieberman also examines the role of artificial intelligence and political polarization, suggesting that these modern developments exacerbate feelings of isolation among individuals. By shedding light on these issues, Lieberman hopes to challenge societal norms and spur discussions about mental health and the importance of community in combating loneliness.
