Sumit Paul-Choudhury, a British physicist and former editor of ‘New Scientist’, argues for the importance of optimism in his forthcoming book, ‘The Bright Side. An Optimistic History of Humanity’. Released on January 28, 2025, he asserts that optimism is ingrained in our nature, albeit influenced by life experiences. Drawing on neuroscience and psychology, he highlights that optimism encourages action and resilience, illustrated through historical figures like Helen Keller and Katalin Karikó. The book offers a nuanced view of optimism as a vital resource rather than a naïve belief.
