"Our brains are more wired for survival rather than for happiness."Īs you turn your attention inward, Professor Kross says you can get stuck and experience the downside of your inner critic's negativity: chatter. We're more likely to stew over a threatening situation, or a stressful encounter, rather than ruminating about a positive memory - a special family dinner, a picturesque sunset stroll with a partner - because the latter doesn't have a lot of survival value. "When we think about the survival value of this stuff, then it makes sense that our brain is negatively biased because there is a huge benefit from thinking that something's going to get us," she says. She says these questions help to explain why it's easy for that internal voice to start fixating on the negative.

Then as we mature it becomes our foremost tool for solving problems and ordering our internal and external world.

So how can you live with the inner critic in your head and not let its chatter take over? Your internal guide He says it can be a force for good, provided we consider "what we can do to harness our voice rather than get controlled by it in the wrong ways". Professor Ethan Kross, a psychologist and neuroscientist at the University of Michigan, has spent the last 20 years researching how we evolved to live with this internal dialogue. That little critic in your head can help you wade through some of life's biggest challenges - but it can also be a cruel tormentor living rent-free in your mind. It can be tough to manage your inner voice.
