Brain scans can identify psychopaths even in childhood because they have no empathy when seeing people in pain

Children who were aggressive or cruel had reduced brain activity in response to images of others in pain

Brain scans can be used to identify children who may be potential psychopaths, new research has shown.

Scientists have found that certain areas of a psychopath’s brain showed a reduced activity in response to images of others in pain.


The regions affected are those known to play a role in empathy, the ability to relate to other people’s feelings.

Scientists say the patterns could act as a marker to single out children at a risk of becoming adult psychopaths.

A total of 55 boys aged 10 to 16 were assessed in the study.

Of these, 37 met the criteria for children with ‘conduct problems’ (CP) according to questionnaire answers provided by parents and teachers.

CP children display a plethora of antisocial traits including aggression and dishonesty.

Like the central character in Lionel Shriver’s novel…

Strategic thinking involves emotions

Posted on

Many of us think that strategy is a higher level activity than its actual execution.

Even business schools make a distinction between strategy and operations and managers are urged to become more strategic if they want to progress.

However both kinds of thinking draw on socio-emotional reasoning and more so for the more adept strategists. Researchers in the USA asked managers to react to fictional strategic and tactical management dilemmas whilst measuring their brain activity using functional magnetic resonance imaging (fMRI).

The researchers were particularly interested in how different areas of the brain interacted. The pre-frontal cortex is the executive part of the brain and normally associated with strategic thinking ie pattern recognition, risk assessment, abstract thinking, and anticipation.

Whilst these abilities help managers solve problems the researchers found that in the best strategic thinkers there was less neural activity in that region and more in the areas of the brain associated with instinctive reactions, empathy and emotional intelligence viz the insula, anterior cingulate cortex and the superior temporal sulcus.

The conscious executive function was downplayed whilst the regions associated with unconscious emotion processing was operating more freely.

Furthermore the strongest performers’ tactical reasoning relied not only on the emotional processing part of the brain and that part used for making choices based on past decisions, but also the part of the brain used to anticipate other people’s thoughts and emotions.

So although IQ based reasoning is valuable in both strategic and tactical thinking high performers have the ability to take a more holistic approach by integrating their brain processes. Strategic thinkers may even repress rational thought to allow their emotional and intuitive processes freer reign.
