Hmmm..sometimes I think researchers have too much time on their hands. Perhaps "Tom" the scientist gets a better reaction from colleague "Jenny" (or "John") during a coffee break than during after-work drinks. Perhaps it may be more to do with quantity consumed than the temperature of the drinks but it also depends on whos buying!
Judgment of character can be influenced by something as simple as the temperature of a drink held in our hands, according to a US study published today.
Researchers from Yale University conducted experiments that showed that people perceive others as more generous and more attentive if they have just been holding a hot cup of coffee, and that the inverse is true for cold drinks.
A second study found that people are more likely to give something to others if they held something warm, and more likely take something for themselves if they held something cold.
