You are starting from the hypothesis that your understanding scientific method is correct and complete, and that everyone else has the same understanding. Neither of which is sustainable from the evidence here.

There are no 'weaknesses' with scientific method, publishing and grants are issues of personality not science, as even scientists have personalities. You are correct in suggesting a hypothesis can not be 'proven' true but that is its the primary strength, and not an inherent weakness as you imply.

At its simplest, scientific method is a process for producing useful explanations for how the universe works. It is a stunningly simple process with only four steps:

1. observe a phenomenon
2. produce hypothesis to explain it
3. use hypothesis to predict previously unseen phenomena
4. experiment to observe unseen phenomena.

If phenomena matches predictions, then hypothesis is useful because it describes what is there AND it led to new knowledge. If phenomena not observed or doesn't match predictions, then either experiment is insufficient or hypothesis is not useful.

It has been suggested that it should be match reality, but this is not correct (or at least is misleading) as demonstrated by both Relativistic and Quantum physics, where the theories were completely outlandish when proposed and it was years before experimentation could confirm their predictions.

It does not matter who comes up with the idea, nor does it matter who performs the experiment, so it is free from bias in that respect. Also, anybody can show that any idea is incomplete if they come up with the appropriate experiment that shows predicted results are not there or not correct, but this does not make the hypothesis false (since it was never 'true' to begin with) it simple puts limits on its usefulness. Newtons laws of motion will put a satellite in space, so they are clearly useful, but if you want accurate GPS then you need to use the improvements and refinements proposed by Einsteins theories on relativity.
