The Science of Indecisiveness
Pizza or Pani Puri? KK or One Direction? Read a book or binge a TV show? We've all been confronted with 'crucial' life choices but many a time, when under pressure, it is common to feel paralysed; so yes, don't worry - you're not the only one. In fact, scientists have found that nearly 20% of the adult population suffers from this. Why? Let's find out! Researchers have found that the stability of preference-based decisions relies on the intensity of communication between two specific areas of the brain, rather than the strength of activation in individual brain regions. To investigate this, they employed transcranial alternating current stimulation, a non-invasive technique that modulates brain activity patterns. They reduced information flow between the prefrontal cortex (located just below the forehead) and the parietal cortex (above both ears) while participants made preference-based or sensory decisions about food. The study revealed that when the informati
