Study 1: Prefrontal white matter in pathological liars
"Results: Liars showed a 22-26% increase in prefrontal white matter and a 36-42% reduction in prefrontal grey/white ratios compared with both antisocial controls and normal controls."
More white matter in the prefrontal lobe = more inclined to lie and manipulate people
Another group of researchers followed up on this same study 2 years later and found similar results
Study 2: Localisation of increased prefrontal white matter in pathological liars
"Liars showed a relatively widespread increase in white matter (23–36%) in orbitofrontal, middle and inferior, but not superior, frontal gyro compared with antisocial and normal controls. This white matter increase may predispose some individuals to pathological lying. "
Why does this matter? Well based on another study, women have noticeably more prefrontal white matter than men, making them more prone to lying pathologically
Study 3: The neuroanatomy of general intelligence: Sex matters
"Compared to men, women show more white matter and fewer gray matter areas related to intelligence. In men IQ/gray matter correlations are strongest in frontal and parietal lobes (BA 8, 9, 39, 40), whereas the strongest correlations in women are in the frontal lobe (BA10) along with Broca's area. Men and women apparently achieve similar IQ results with different brain regions, suggesting that there is no singular underlying neuroanatomical structure to general intelligence and that different types of brain designs may manifest equivalent intellectual performance. "
Women have more white matter in the frontal lobe, while men have more grey matter there. Here's a picture below from that same study to help you viusalize it
Worse yet: 86% of women's white matter dedicated to intelligence is located IN THE FRONTAL LOBES, compared to 0% (ZERO) for men
"Even greater sex differences were observed in WM (white matter), where for women 86% of the identified voxels were frontal, as compared to 0% in men."
Conclusions?
Women are much more inclined to lie because of the very structure of their brain. For them thinking and manipulating are closely related because so much of their brain power is involved in deceit
A question worth raising is: Are you born with this or is this a product of behaviour? Well according to study 2 it can be both.
" One interpretation of the white matter increases in the ventral and lateral non-superior frontal regions could be that a pre-existing variation in prefrontal structure may predispose individuals to engage in pathological lying. Alternatively, several studies have argued that long-term training may induce regional increases in white matter volume (Schmithorst & Wilke, 2002; Bengtsson et al, 2005). In the case of lying, it is conceivable that excessive lying repeatedly activates the prefrontal circuit underlying lying, resulting in permanent changes in brain morphology. This 'Pinocchio's nose' hypothesis of pathological lying could be compared with the competing predisposition hypothesis using a prospective longitudinal study assessing both white matter volume and degree of lying from childhood to adulthood.

Some people are born liars. But lying constantly can rewire and rebuild your brain to make you naturally even more prone to lying ...
