179,"BFI2D is calculated by dividing the BFI by an expression that increases with the directional spread and decreases with the peakedness. It comes from the consideration that an increase of the directional spread reduces the excess of kurtosis, which is not taken into account in the BFI alone. Mori, N., M. Onorato, and P. A. E. M.
