 This is scientific Americans 60 second science.I'm Eric Barris.Got a minute? We all have that friend,the Debi Donner who finds fault with sunshine and lollipops¹ and see their perpetually half empty glass.Well it turns out being such a drag might be part of their individual personality.As mention  researchers are calling dispositional attitude.A new study says people with a negative dispositional attitude,well,as a rule,dislike things,all things.In other words,haters than a hate.Researchers created a skill that require people to report their attitudes towards things like architecture in camping.They found people with positive attitudes were generally open and curious,and headends follow positive behaviours like recycling and driving carefully.Then negative allies? Not so much.The study is in the journal of personality and social psychology².Researchers say this personality trait could also be used for marketers.why convincing those with a negative dispositional attitude to like their product? They could just convince them to dislike everybody else's.Thanks for the minute.For scientific Americans 60 seconds science,I'm Eric Barris.
