Gut instinct may stem from heart

A new study probes what prompts people to make the decisions they do.

It suggests there is indeed a link between your heartbeat and the decisions you make.

Researchers say the emotional parts of the brain generate the bodily response -- for instance, the heartbeat.

The rational parts of the brain then listen in to these bodily responses to find out what the emotional parts of the brain are doing. This allows both logic and emotion to shape our choices.

The findings don't indicate that your heart is very good at giving you insight into what to do, but authors say the study manages to find evidence that's there's something to the idea of trusting your heart.

It's published in Psychological Science.
