Title: A wandering mind is an unhappy mind.

Summary: I’ve taken a step back with this study (chronologically speaking) because it predates the Jazaieri et al. paper that I recently reviewed. According to Google Scholar, this investigation has been cited by other researchers over 1500 times. If you read any scientific study linked to mind wandering since 2010 you can expect to find Killingsworth & Gilbert referenced. Three reasons why this work is so popular, firstly it was a big study, recruiting 2250 participants. Secondly, it took an innovative approach to the use of technology, using an iPhone app to track and record mind wandering in ‘real world’ scenarios. Finally, the study made some very strong statements which with hindsight, have perhaps oversimplified mind wandering. In particular, the idea that “a human mind is a wandering mind, and a wandering mind is an unhappy mind”.

The full purpose of mind wandering is not yet understood, its activity is largely observed in the Default Mode Network (DMN). The DMN is a collection of anatomically separate regions that are most active when we are not engaged in a specific externally focussed task, hence our ‘default state’. The research concludes that mind wandering is a cause of unhappiness and (staggeringly) even mind wandering to positive subjects doesn’t appear to improve self-reported happiness. Provided with this kind of context it’s no wonder that the idea of suppressive mind wandering approaches maintained popularity across experimental and clinical psychology. Killingsworth & Gilbert even supported their case by claiming that many religious and philosophical traditions link happiness to living in the here and now.

Buddhism and mind wandering

Many forms of meditation and mindfulness do work on training consciousness to rest in the present moment. But from the Tibetan Buddhist perspective to equate this with a conclusion that mind wandering is a cause of unhappiness is somewhat misleading. Traditional meditation is often set in a wider context, undertaken for the benefit of all beings (self and other). Any merit that is accumulated from resting in the present moment is typically dedicated to others, rooting the practice in the past present and future. The idea that a thought, rather than the reaction (attachment or aversion) to the thought is the cause of unhappiness isn’t supported by the theoretical frameworks of traditional meditation systems.

Abnormally high levels of mind wandering are likely to be clinically problematic, but even today we don’t know all the functions mind wandering might have. It’s considered to be linked to the narrative we make to understand ourselves in the wider world. There isn’t evidence that the process itself brings unhappiness, it may be that the quality of our self-generated narrative rather than mind-wandering per se might be the problem. For example, 1 in 4, 14-year-old girls in the UK demonstrate symptoms of depression, and that teenage depression is correlated with social media use. Can we say that mind wandering to social media content, rather than emotions linked to social media content is the root cause of any reported unhappiness?

Who you really are; the default mode network

The default mode network has a crucial but poorly understood role in how meditation influences brain structure and function. This paper sets out some of the current thinking regarding self-generated thought.

Title: The default network and self‐generated thought: component processes, dynamic control, and clinical relevance

Summary: It is frequently suggested that neuroscience is still in its infancy, this becomes patently clear when you start to consider how little we know about the default mode network (DMN). The DMN, also known as the default network (DN) or the task-negative network (TNN) is most active when humans are in a resting state. In short, the DMN is the network that takes over when we are not actively engaged in a specific task. Surprisingly it was assumed that the brain was resting when not engaged in an externally focussed activity. This assumption was surprising because scientists know that their brains are capable of complex processes such as mind wandering when they are not reacting to the external environment. However, only when it was demonstrated that functional brain activity could reach similar levels in task and non-task modes did the investigation into the DMN begin in earnest. This has particular relevance for meditators and contemplative science, as the DMN is often the direct and indirect target for meditation methods.

Andrews‐Hanna,  Smallwood and Spreng produced a review of the leading findings linked to the DMN, which they describe as an anatomically diffuse global network.  Their primary focus is the DMN and self-generated thought, thought that arise without external sensory stimulus. Describing much of the recent research in the field they conclude that the DMN plays an integrated role in a wide range of neurological functions. Thus both normal and abnormal mental health is dependent on activity and functional connectivity within the DMN and links to other neural networks. The paper provides a useful background to contemplative scientists looking for an understanding of how meditation might influence human behaviour.
