“Personality” connected to White Blood Cell Count

This gives me goosebumps ….

With each passing day more and more research is being conducted and published on the direct connection between our Natural Personal Temperament and our Biology.

I have tracked 100’s of papers making this connection going back decades…but sadly or rightly they were conducted using an MBTi / DISC tool that has been fundamentally dismissed by the scientific community. The Big 5 seems to be the agreed upon go to Gold Standard.  The MBTi(1943) not only is the worlds most common Personality Psychometric but had a 40 year lead on the Big 5/ FFM/NEO (1985) so its not surprising scores of PHD papers were done using the MBTi as the tool de jeur.

I have worked , designed , facilitated psychometric testing to 1000’s for 3 decades and am fascinated by conflict and how our temperaments are connected to Biology and Management/Economics …student of Drucker and Eysenck

Impulsivity-related Traits Are Associated with Higher White Blood Cell Counts


A chronically elevated white blood cell (WBC) count is a risk factor for morbidity and mortality. The present research tests whether facets of impulsivity – impulsiveness, excitement-seeking, self-discipline, and deliberation – are associated with chronically elevated WBC counts. Community-dwelling participants (N=5,652) from Sardinia, Italy, completed a standard personality questionnaire and provided blood samples concurrently and again three years later. Higher scores on impulsivity, in particular impulsiveness and excitement-seeking, were related to higher total WBC counts and higher lymphocyte counts at both time points. Impulsiveness was a predictor of chronic inflammation: For every standard deviation difference in this trait, there was an almost 25% higher risk of elevated WBC counts at both time points (OR=1.23, 95% CI=1.10–1.38). These associations were mediated, in part, by smoking and body mass index. The findings demonstrate that links between psychological processes and immunity are not limited to acute stressors; stable personality dispositions are associated with a chronic inflammatory state.
