(CNN) -- Worried that the 27-year-old man making more than ,000 as profiled on an online dating service isn't so young or taking home that much cash?
Research involving more than one million online dating profiles was partly financed by a grant from the National Science Foundation.
But those saying they were most likely to lie generally gave answers to other questions indicating they were people pleasers, or "high self-monitors." Such people have an acute sense of what others like and control their own behavior accordingly for social ends.
Because they want to be liked and fit in, these people, whether online or off, may lie about weight, age, income and interests, Hall said.
Evolutionary Psychology suggests that women are more likely to look for men that have more resources and are committed for the long-term.
Both of these traits show that the man is willing and able to take care of any future offspring in the long-term.
