Not sure what studies you’re reading, every field handles reproduction step in their a tad paper differently. In my old field (neuro roughly) its assumed the reader has enough familiarity with laboratory work and related concepts/jargon that by looking through the methodology section and the logic put forth in the rest of the paper they could figure out what the OG papers’ authors had in mind and recreate the study. This is also a knowledge gate depending on the field since it may or may not require additional knowledge of stats, research design and so on, and can be an unfortunate thing about science in its current state.

Back when I was in school if something was a little rough you could see something played out in real time for some papers on JoVE (Journal of Visualized Experiments), but now Youtube, bio hackerspaces, and Tiktok are bigger so if you were a bit confused you could look at those for basic stuff.

I hope that helps and wasn’t too rambly.
