If you want someone to feel better pre-disposed to you offer them a hot drink rather than a cold one.
Researchers at Yale University asked participants in their study to rate the personality traits of a fictitious person after asking them to hold a cup of coffee – either hot or iced.
They found that those who had held a hot drink rated the person as more generous, sociable and good-natured compared to those who had held a cold drink.
The researchers say we are more sensitive to cues from our physical environment than we might think.
Previous research found that the size of paper used in presentations had a greater impact and the weight of clipboards used to hold CVs influenced recruiters’ impressions (a weightier candidate)
