In the first half of the 20th century, people with TB were advised to stop kissing to protect their friends and family from contracting the dreaded disease. In 1905, delegates at an International Congress on Tuberculosis in Paris described kissing as “dangerous, detrimental and responsible for countless diseases”. 

My wife Marie and I are a mixed couple. She's Canadian and I am an American. For the past 15 years we have spent our winters in Florida and our summers in Nova Scotia.

Do we understand why and how people change their mind about climate change? Is there anything we can do to engage people?

We cannot psychoanalyse Trump from a distance, though I am sure many of us have tried. We can, however, apply psychological theories and models to understand the denial of defeat.

Trust is a crucial component of effective public health policy. It is also a two-way street. People need to trust the authorities – universities, employers, the government – that are asking them to behave in a certain way, but they also need to feel trusted by these authorities.

The success of second lockdowns around the UK will depend not just on people following the general rules but also on positive cases and their contacts self-isolating entirely.

COVID-19 has been a humbling experience. From a frayed pandemic early-warning system to a shortage of personal protective equipment for front-line workers, public health experts have been playing catch up. But it has also been a teachable moment.

Children are naturally inquisitive and tolerant. Many constantly ask questions. At some point, most of them – most of us – just stop. Why does this happen?

The medieval Japanese experienced crises that inflicted tragedies and unexpected deaths on many ordinary people

Many of us have been holding back and storing unfelt emotions. What's the purpose? Unfortunately, the reason behind suppressed emotions is self-defeating. Holding back from "feeling your feelings" is usually how we try to protect ourselves from being hurt. However...

A new study explores why people make a “non-click” choice, a decision to not respond to some social media posts, even when they spend time as “lurkers” of the content.

The Centers for Disease Control and Prevention recently revised its guidance to acknowledge that COVID-19 can be spread through tiny airborne particles, known as aerosols.

As a psychologist whose specialty is treating men, I believe that behind many of the threats we face are the invisible, dangerous, dysfunctional and persistent beliefs that manhood is about power and control. These beliefs about what it means to be a man are what I refer to as “confined masculinity.”

Women politicians are more responsive than men when people come to them seeking health care and economic support, our newly published study on gender and government responsiveness reveals.

Scientific analysis of COVID-19 is dominated by medical and pharmaceutical questions of vaccines and risk minimisation.

Many of us believe we are masters of own destiny, but new research is revealing the extent to which our behaviour is influenced by our genes.

Suffering from pain causes consumers to spend more money than they otherwise would – perhaps 20% more – according to new research I conducted.

I’m seeing quite a few “climate-friendly” products at the supermarket. Are consumers willing to pay more for these? And how can we encourage people to make good choices?

Why are some humans cruel to people who don’t even pose a threat to them – sometimes even their own children? Where does this behaviour come from and what purpose does it serve?

As a scholar, I have examined the circumstances that can prompt victims to change their stories about sexual assault.

We spend so much time helping people who punish themselves and constrain their lives with an overdeveloped sense of guilt that it's easy to forget the other side of the coin.

Do you feel like you're never enough? That there's never enough time? Money? Friends? Great opportunities? Recognition? Do you believe if you had or did something else...

Feeling torn about wearing a mask? Me too. I don’t want to look like I’m virtue signalling or get funny looks. But I also want to be responsible about public health.
