Being open-minded literally changes the way you see the world

openness to new experiences is linked with creativity... we’re constantly filtering out what sensory information to focus on.... “The ‘gate’ that lets through the information that reaches consciousness may have a different level of flexibility... Open people appear to have a more flexible gate and let through more information than the average person.”...
those who score high in openness are less likely to experience “inattentional blindness.”... when people are focusing so hard on one feature of a scene that they completely fail to notice something entirely obvious...
training can make people more open to new experiences.
