The latest world happiness report was recently published, casting Finland as the happiest place on Earth. But how do you really measure happiness? When we’re sad or suffering from poor mental health, psychologists encourage us to remember sadness is a feeling and it will pass – why not the same for happiness? And as anyone who has plastered on a smile to get through a social engagement on a bad day will know, happiness is easy to fake.

Researchers at Lund University were also skeptical and carried out a study to find out what people were really thinking of when presented with the same question asked to participants in the world happiness ranking. They found that often people are thinking about wealth and status and that, actually, most of their participants didn’t want to be on the top rung of the “best life possible” ladder.

Meanwhile, it has been ten years since the word “aphantasia” was coined, describing people who have never been able to visualise things in their mind. Read this fascinating explanation of what we have learnt about aphantasia in the last ten years, by the researcher who first came up with the term.

And as Easter approaches, we tackle the burning theological question of why Jesus is sometimes depicted with a six pack.
