Where Psychology and Sociology Get It Wrong

What prevents psychology from being completely successful?

If you have ever been through difficulty of the mind whether trauma, mental illness, and/or great struggle in one's life, then you have experienced something of what psychology and sociology have to offer. This has been a great help for many, yet something is missing. Accuracy is calculated by the following formula ((Observed value - target/actual value) divided by the target/actual value). Psychology/Sociology can find a regression or trend line of the human data points. This makes these sciences a "science of the norm" instead of a "science of law". Neither sociology nor psychology understands its object in its true context, and still more, do they evaluate humanity by objective criteria.
