A Study of First Love at Sight and Marriage Stability with Digit Ratio

The digit ratio is the ratio of the lengths of different digits or fingers on a hand. The 2D:4D ratio is the most studied digit ratio and is calculated by dividing the length of the index finger of a given hand by the length of the ring finger of the same hand. Digit ratio is the measurement of prenatal testosterone hormone. Small 2D:4D ratio or digit ratio points the high exposure to testosterone in the uterus. Men having lower digit ratio is more sexual where as women with higher digit ratio are more prone for affection and care for love. Thus, male sex and female affection varies with the variation of digit ratio. Digit ratio of 602 numbers of men and women are studied by Matteo M Galizzi and Jeron Nieboer is taken in this paper as a reference. Then, it is a normal distribution and the graph is plotted taking Y axis which represents any relationship among the certain number of males and females and X axis which represents digit ratios of the males and females. The probabilistic analysis of the normal distribution of the sample study is evaluated. In the sample study for a sample of two-digit ratios of one male and one female are chosen arbitrarily which lies left from the mean and right from the mean respectively. The area curve represents the marriage stability probability. The probability of the area curve is calculated. If the area of the curve is more the stability of the marriage is more and if the area of the curve is less than the probability of the stability of the marriage is also less. It declares that the men with higher digit ratio is more comfortable to choose a female partner with high digit ratio as the area under the normal distribution curve is more for the lower digit male and higher digit female and marriage stability index is also more. The area under the curve is less compared to the higher digit male and lower digit female and regarding the case marriage stability index is less. If the marriage stability index is greater than 0.5 it is considered a healthy marriage and if it is less than 0.5 is not regarded as a healthy marriage. For first sight love one digit ratio should be known. Then the area under the curve that is probability is equated from mean and the other unknown digit is calculated. This two-digit ratios holding same area from the mean is more reluctant to fall at first sight love. The hypothesis is checked by statistical testing. In 0.01% case it is expected to fall and the hypothesis is rejected and in 99.99% case the hypothesis is accepted. Women mind are always having lover provider duality which in 0.01% case the women is more affectionate for husband or second lover where as in 99.99% case the women is reluctant to choose the first lover from her affection choice. But it is not possible always to maintain this affection for social aspects and it is surpressed. Economical aspects are not studied regarding the issue.
