How often do you go on first impressions? Have you ever made a snap judgement about someone? You could be falling victim to cognitive bias

What is cognitive bias? The halo effect and horn effect

You might have heard the expression, ‘the first impression is the last impression’, meaning it’s hard to change an opinion of someone once it’s formed. Sometimes, we make quick decisions about people and without realising we rely on biases to do this.

The ‘halo or horn effect’ is a cognitive bias where our impression of someone influences how we feel about their overall character. Our brains are trying to categorise copious amounts of information based on previous experiences and memories. But sometimes this isn’t so reliable and we make a biased positive or negative opinion of someone. An easy example to highlight how we might do this is by putting more trust in someone who is an authority figure than someone who is not.

What is the ‘halo effect’?

The ‘halo effect’ is an unconscious bias in which our impression of a person influences how we feel and think about their character. It says that a positive impression of someone in a single area positively influences our feelings of that person in other areas. Kathryn Wheeler at Happiful explains the origins of the halo effect in her article, What is the halo or horn effect and how does it affect workplace culture?

“The concept has its origins in the work of 1920s American psychologist Edward Thorndike. In an experiment, Thorndike asked commanding officers to rate the physique, intelligence, leadership, and character traits of soldiers, before having any interactions with them. What he saw was that when the officer gave a soldier a high rating in one category, they tended to also give them high ratings in the others, too. He named this the ‘halo effect’.”

The expression ‘halo’ refers to the concept sometimes found in religious art, meaning we see that person in an overly positive light. Once the ‘halo effect’ has a good grip on us, it’s difficult to think in a neutral way when evaluating others. One common example of this is when we judge someone’s character based on how attractive we find them. Some people believe that attractiveness affects how we perceive that person’s personality. Certain marketing campaigns use this idea to help sell products. The opposite of this is making negative assumptions about someone’s personality based on how unattractive you may find them. This is known as the ‘horn effect’.

What is the ‘horn effect’?

The ‘horn effect’ is the other side of the coin, when a negative impression of someone in a single area, negatively influences our feelings of that person in all other areas. As with the ‘halo effect’, our brains can go into time-saving mode, making snap judgements based on experiences and memories. Even what mood we are in that day can influence the way we unconsciously categorise someone. It can show up in many ways: when choosing which products to buy, who to vote for, who you want to be friends with, who to date, and where to liv

Along with all the ice cream that everyone is making, this copycat Hershey’s syrup has become one of the most popular recipes on the website over the past few months. It’s been fun to see what we can make from home instead of immediately running to the store.

Homemade Chocolate Sauce

When I first made this, I wanted a simple homemade chocolate syrup similar to Hershey’s syrup; something that I could use to make chocolate milk for my boys or use as an ice cream topping.

Over the past few years, I’ve made numerous chocolate sauces: rich creamy hot fudge sauces and basic melted chocolate sauces (i.e. Homemade Magic Shell).

Top your ice cream with homemade chocolate sauce for an awesome treat!

I ran across this chocolate sauce recipe many years ago and tried it within a few days of finding the recipe. This was exactly what I wanted!

The sauce is not overly sweet and it is smooth and rich in flavor. This is even better than the Hershey’s syrup that I remember. I am excited to have this in the refrigerator now and I can hardly wait to make a treat with it after dinner tonight!

How To Make Chocolate Syrup

When I found this recipe for homemade chocolate sauce, it was almost too simple to believe. No fancy ingredients, no dairy, just sugar, cocoa powder, and water. A pinch of salt and a tiny splash of vanilla finish it off perfectly.

This sauce tastes like Hershey’s syrup, only better. The fact it’s so incredibly easy to make means there is almost always a jar of this chocolate syrup in my refrigerator.

Michelle Elman on how to learn to ask for help

Why do we feel so much pressure to be self-reliant, and how come it is so hard to accept a helping hand? Columnist Michelle Elman delves into our curious obsession with independence, and the life-changing realisation that allowed her to welcome support

Michelle Elman on how to learn to ask for help

We live in a culture that encourages us to be strong and independent, but is it possible that we have gone too far? When there is so much pressure to do everything yourself, is it any wonder that we associate weakness with relying on other people?

Alongside the ‘strong independent woman’ trope that has been sold as an aspirational goal, I believe part of what has caused this is the fearmongering around being ‘codependent’. Codependency was defined by Melody Beattie, in her book Codependent No More, as “one who has let another person’s behaviour affect [them] and who is obsessed with controlling that person’s behaviour.”

Of course, codependency brings its own set of problems, but have we run so far away from codependency that we are now on the opposite end of the spectrum: hyper independence?

Hyper independence is the belief that you are the only person you can rely on. It is often born out of a trauma where you have relied on someone in the past and been let down, so, as a result, you have a “if you want something done, you have to do it yourself” mentality. Consequently, instead of understanding that relying on others is not only normal, but necessary, you feel shame for not being strong enough to go it alone.

I used to be the same. The thinking behind my behaviour was that if I relied on someone, asked them for help or even just a favour, that made me vulnerable, and when you are vulnerable you are exposing yourself to being hurt. What I ignored was that the immense pressure I put on myself to do everything alone was incredibly isolating and, in fact, blocking me from forming genuine and intimate connections, because in order to ask for help, you need to allow yourself to trust others and let them in. And yes, that’s scary! But it’s worth it.

I tell the story in which I learned this myself in my new book, The Selfish Romantic. I had just come back from a funeral when the guy I had been on three dates with checked up on me to see how I was. Being so used to being single, and very hyper independent at that point, I shut down the conversation and said he didn’t need to worry, to go out with his friends, and I’d speak to him the next day. Hours later, he turned up at my door simply saying: “I thought you might want a hug,” and he was right. I really did.

Later that night, I said to him that it was really kind of him, but he didn’t have to come over and that I would have been fine. His response? “I know you would have been fine, but just because you can do it alone doesn’t mean you have to.” It taught me a valuable lesson to not only ask for what you need, but it was actually OK to ask if you didn’t need it, but you simply wanted it. I didn’t need a hug, I would have survived without one, but I sure did want one!

Letting someone in is terrifying. I was right, letting people in gives them potential to hurt you and use your vulnerability against you. But living a life where you don’

Six times as likely to die by suicide: the Traveller mental health crisis

It’s time to take a hard look at the reality faced by many in the community

Six times as likely to die by suicide: the Traveller mental health crisis

“I’m from the north-west of England, a little town called Morecambe Bay, not far from the Lake District. My family are Showmen Travellers. My mam, she grew up around the Bolton area and her family all had fairgrounds and travelled around the whole of the UK. My dad, he actually came originally from a circus and fairground background. They met and hit it off – not initially, but they got there. And then they decided to have an amusement arcade, so they settled.”

I’m speaking to Xenna Kaser, a counsellor who is also part of the GRT (Gypsy, Roma, Traveller) community. GRT is an umbrella term for those who belong to minority ethnic groups such as Irish and Scottish Travellers, and Romany people, as well as New Travellers, Showpeople, and Boaters. It’s estimated that there are around 300,000 Travellers in the UK, and those in the GRT community share a distinct, diverse, and rich heritage.

“We all went through school still going to those fairgrounds, the big ones in particular, throughout the year to meet friends and socialise,” Xenna continues. “Neither I nor my two brothers have gone into the field. We’ve all gone on to do different things, but are still very much in touch with our background.”

Xenna’s vocation as a counsellor working with the GRT community is an incredibly valuable one. Alongside the everyday joy that comes with family and community, Travellers are one of the most persecuted and marginalised groups in our society. In fact, it was only in 2021 that ‘Roma’ was included as an ethnic group, and ‘Showman’ as an occupation and ethnicity, in the England and Wales Census. And while there is a severe lack of legal sites for Travellers, in 2022, the controversial Unauthorised Encampments: Police, Crime, Sentencing and Courts Act made residing with a vehicle on land without permission a criminal – rather than a civil – offence, giving police the power to seize vehicles and, consequently, people’s homes and way of life. With all that in mind, it goes without saying that living in this environment can take its toll.

Six times as likely to die by suicide: the Traveller mental health crisis

The suicide rate for Travellers is six times the general population

That’s according to a study by All-Ireland Traveller Health, and the figure rises to seven times the general population for men. Another survey found that 82% of the Travellers surveyed had been personally affected by suicide.

“I’ve known people who have taken their own lives, and it’s really devastating,” Xenna says. “I think there are a number of factors behind it. One, is that it’s a relatively closed community and it is very misunderstood – so I think people who are having problems, if they were to go to a doctor or a therapist who hasn’t been briefed on the community and how the community works, they could feel quite misunderstood and, therefore, that leads to a lot of shame.”

Xenna’s insight rings true. In January 2019, the Government published its first-ever cross-government Read more

What is trauma-informed nutrition and how can we use it to support recovery?

Exploring the complex ways traumatic experiences impact us, and the essential reason why practitioners and clients must be aware of it

What is trauma-informed nutrition and how can we use it to support recovery?

Discussions concerning trauma tend to centre around the mental, emotional, and physical impacts of traumatic events. But in recent years, this has expanded to explore the relationship between nutrition, trauma, and physical and mental health. Let’s take a closer look.

What is trauma?

The charity Mind speaks of emotional or physiological trauma as the result of very stressful, frightening, or distressing events which cause lasting harm, even if the harmful effects are not immediately obvious.

Adverse childhood experiences (ACEs) are harmful events that can occur from as early as in the womb through to age 17, and do not have to be remembered by the child to be traumatic. Examples include experiencing violence, abuse, neglect, or household dysfunction, and adversity including bullying, poverty, war, natural disaster, discrimination, pandemics, medical trauma, and involvement with child protective services. According to the California Centre for Public Health, up to six in 10 people have experienced at least one ACE, and one in six have experienced at least four.

Expanding trauma from the individual to the collective experience, Historical Trauma is that which is experienced by ethnic, racial, or cultural groups over generations – such as slavery, the Holocaust, and colonisation. Then there is Systemic Trauma, which refers to the environments and institutions that contribute to traumatic experiences.

Trauma is multilayered, and has the potential to impact our daily lives. The lasting effects are present irrespective of how or when the trauma occurred. So, the question is: how can trauma-informed nutrition support clients more effectively?

Trauma and nutrition

For some, adverse food-related experiences can be a source of trauma. This includes unreliable or unpredictable meals, imposed restriction or control of food,body shaming, and reward or punishment using food. Trauma may also impact food habits and result in eating disorders and disordered eating, food addictions, high fat, salt or sugar diets, an over reliance on convenience food, and poor food budgeting and planning.

According to Mind, people who have experienced trauma have an increased risk of chronic and long-term illness, including severe obesity, heart disease, strokes, and diabetes. To effectively support their clients, nutrition practitioners who aim to address root causes of illness understand that trauma is a contributory root cause for illness and disease.

The gut/brain axis is central to discussions about trauma and nutrition. Through the vagus nerve, there is a two-way communication between the gut and the brain using hormones, such as adrenaline and cortisol, which influence our feelings and mood. It explains why we may feel nervous jitters in our stomach, have looser stools when stressed, or feel nauseous when in distress. Our gut microbiome directly impacts these hormonal messages, so a healthy gut can support this process.

Trauma-informed nutrition

This approach acknowledges the role adversity plays in a person’s life, recognises symptoms of trauma, and promotes resilience. As noted by the California Department for Public Health, trauma-informed nutrition und
