#38 – Yew-Kwang Ng on ethics and how to create a much happier world

Will people who think carefully about how to maximize welfare eventually converge on the same views?
The effective altruism community has spent the past 10 years debating how best to increase happiness and reduce suffering, and gradually narrowed in on the world’s poorest people, all sentient animals, and future generations.
Yew-Kwang Ng, Professor of Economics at Nanyang Technological University in Singapore, worked totally independently on this exact question since the 70s. Many of his early conclusions are now conventional wisdom within effective altruism – though other views he holds remain controversial or little-known.
For instance, he thinks we ought to explore increasing pleasure via direct brain stimulation, and that genetic engineering may be an important tool for increasing happiness in the future.
His work has suggested that the welfare of most wild animals is on balance negative and he hopes that in the future this is a problem humanity will work to solve. Yet he thinks that greatly improved conditions for farm animals could eventually justify eating meat.
And he has spent most of his life forcefully advocating for the view that happiness, broadly construed, is the only intrinsically valuable thing.
If it’s true that careful researchers will converge as Prof Ng believes, these ideas may prove as prescient as his other, now widely accepted, opinions.
Born in Japanese-occupied Malaya during WW2, Kwang has led an exceptional life. While in high school he was drawn to physics, mathematics, and philosophy, yet he chose to study economics because of his dream: to establish communism in an independent Malaysia.
