Social Media and Youth Mental Health

On 14th November there was an interesting conference at the Royal Society of Medicine on the effects of social media on mental health.

Mary Aiken (University of College Dublin) discussed the Cyber Effect, her book which addresses the risks of social media on young people (cover below). Cyber space is a space and we need to consider the impact of it on vulnerable populations such as teens. We need to factor in developmental aspects (at what age should parents let children have a smartphone?). We need to recognise the continuous evolution of behaviour and as experts we need to drive policy initiatives and develop guidelines for parents and educators.

Jon Goldin (Great Ormond Street Hospital) talked about the risks and benefits of social media for young people. Children like using social media for different reasons: they use it for communication, to express themselves, to gain confidence, for popularity, for entertainment, to develop a sense of belonging, to receive information. Social media is risky for adolescents: it may cause a lack of sleep; due to anonymity, it encourages bad behaviour such as cyberbullying; it may facilitate gambling; and it can be used to research suicide methodology.

The worrying data suggest a correlation between social media use and mental health issues. There can be advantages to the use of social media such as ready availability of information, but the reasons to worry are greater than the reasons to be optimistic unless measures are taken to regulate the use of social media. One worry concerns anorexia nervosa: whereas some sources offer support there are sites inviting people to be anorexic and offering tips to avoid food. Another worry concerns child protection such as preventing grooming and sexting.

What are the possible solutions to these problems? There needs to be more education (sex education and internet security in schools). There needs to be an acknowledgement that social media has good effects, an open discussion about it with adolescents. Social media cannot be banned entirely but there needs to be boundaries, such as no more than two hours of social media a day and no social media in the bedroom after a certain time.

Rationalization: Why your intelligence, vigilance and expertise probably don't protect you

Today's post is by Jonathan Ellis, Associate Professor of Philosophy and Director of the Center for Public Philosophy at the University of California, Santa Cruz, and Eric Schwitzgebel, Professor of Philosophy at the University of California, Riverside. This is the first in a two-part contribution on their paper "Rationalization in Moral and Philosophical thought" in Moral Inferences, eds. J. F. Bonnefon and B. Trémolière, (Psychology Press, 2017).

We’ve all been there. You’re arguing with someone – about politics, or a policy at work, or about whose turn it is to do the dishes – and they keep finding all kinds of self-serving justifications for their view. When one of their arguments is defeated, rather than rethinking their position they just leap to another argument, then maybe another. They’re rationalizing –coming up with convenient defenses for what they want to believe, rather than responding even-handedly to the points you're making. You try to point it out, but they deny it, and dig in more.

More formally, in recent work we have defined rationalization as what occurs when a person favors a particular view as a result of some factor (such as self-interest) that is of little justificatory epistemic relevance, and then engages in a biased search for and evaluation of justifications that would seem to support that favored view.

You, of course, never rationalize in this way! Or, rather, it doesn’t usually feel like you do. Stepping back, you’ll probably admit you do it sometimes. But maybe less than average? After all, you’re a philosopher, a psychologist, an expert in reasoning – or at least someone who reads blog posts about philosophy, psychology, and reasoning. You're especially committed to the promotion of critical thinking and fair-minded reasoning. You know about all sorts of common fallacies, and especially rationalization, and are on guard for them in your own thinking. Don't these facts about you make you less susceptible to rationalization than people with less academic intelligence, vigilance, and expertise?

We argue that no. You’re probably just as susceptible to post-hoc rationalization, maybe even more, than the rest of the population, though the ways it manifests in your reasoning may be different. Vigilance, academic intelligence, and disciplinary expertise are not overall protective against rationalization. In some cases, they might even enhance one’s tendency to rationalize, or make rationalizations more severe when they occur.

While some biases are less prevalent among those who score high on standard measures of academic intelligence, others appear to be no less frequent or powerful. Stanovich, West and Toplak (2013), reviewing several studies, find that the degree of myside bias is largely independent of measures of intelligence and cognitive ability. Dan Kahan finds that on several measures people who use more “System 2” type explicit reasoning show higher rates of motivated cognition rather than lower rates (2011, 2013, Kahan et al 2011). Thinkers who are more knowledgeable have more facts to choose from when constructing a line of motivated reasoning (Taber and Lodge 2006; Braman 2009).
