Social sciences do not have absolutes...
Neither do physical sciences. The essence of science is endless refinement and new discovery. Hence, for basic proof, just look at the dates of discovery in the growing periodic table of elements:
The use of First Principles does not have static results, but constant innovation and discovery. Thus it is with social sciences also. The principles are the same, the statistical precision of measurement and thus correlations are different.
There is one highly specific arena in Physics, for example, that has accuracy and precision quote similar to much social psychological research (Response modeling, preferences measurements, etc) and Geophysics (materials exploration, reserves assessment, etc). In both of these, one social science, the other 'hard' science, the correlations and processes are similar.
In specific reference for these two examples there is a specific point. In the -1970's-1980's when LISP was first being deployed the first commercial AI applications were expert systems.
maybe the first, was this:
SRI’s Artificial Intelligence Center developed one of the first computer-based expert systems to aid geologists in mineral exploration.

Slightly later was the deployment of the same technology used in Prospector to deploy an AI commercial lending system at Union Bank of California around 1982.
This example, which i know because I worked on the latter one myself, shows that the approaches and scientific processes for social science and physical science are identical.
Not too many years later my entire team developing commercial and consumer financial decisions was composed of physicists, primarily geophysicist, but others also. In materials calculations fo parts reliability and Mean time before failure (MTBF) and others factors deal with quite analogous statistics with search for low probability, high impact events, such as turbine fan failures in, say, Turbojet engines. Guessing wrong on such issues can produce the De Havilland Comet, DC-10 cargo doors, B737MAX and B787 famous issues.
Sorry to belabor these points, but... the success of SpaceX and Tesla has been driven by an exceptional mastery of these issues, with an amazing ability to find ways to do seemingly impossible things. Much of the materials advances in battery, BMS, motor and manufacturing have been driven by innovation driven by a simple maxim; it si possible to do the 'impossible' by constantly coping with tiny statistical variations. A common word used is 'nano technology'. BY definition, in that world statistical probability reigns.
The is no such thing as certainty in physics. A. Einstein famously said "God does not play dice", but he soon admitted he was wrong.
To be mundane: The Gigapress could not have happened without uncertainly in science.
