Is it true that all scientists anticipate simliar data to be understood the same way.?

Question

For example, the heisenburg uncertaintly principle is valid for all electrons or the atomic structure of hydrogen is valid for all hydrogen atoms.

Answer 1

Your question is "philosophical," i.e. almost impossible to understand. If you are asking whether, at least in theory, different scientists with similar backgrounds will interpret the same data in the same way, then yes. In practice, scientists have their own biases that sometimes interfere with intellectual honesty. People may have invested their entire careers in one interpretation of data and may be loathe to give it up even as data mounts for an alternative explanation, people may be politically motivated to ignore data, etc. Reality is complicated, and most important scientific data doesn't have a simple "yes" or "no" attached, thereby complicating interpretation.

On the other hand, for your specific questions, yes, duh, every physicist would say the Heisenberg uncertainty principle applies to all electrons and the atomic structure of the hydrogen atom describes all hydrogen atoms. These are well-established phenomena (such as evolution and gravity) that are widely-accepted. In the paragraph above I was talking about topics of active current research.
