It is not required for people to consciously falsify data for science to come up with false conclusions.

This is true, but even if it unintentionally falsifies data, other discoveries with correct data will reveal that this other data is wrong, so this theory will be put under question, to see if it holds water. If it doesn’t, than that theory is rejected.

That is what science does, it corrects itself if new more correct data is presented, thus striving for perfection.

The idea is to know everything about everything. This is of corse the goal, which is practically unachievable.
