Peer review...
Too many cooking sites are let's exchange your recipe and end up with either stuff missing or absurdly high amount of sugar (as a rule of thumb divide by 2 the amount of sugar) or a lack of salt/spice even when they're notsimply forgotten.
Published books tends to be a bit better as in principle they're revised.
Peer review is how scientists correct that. Often it's as simple as on figure 2, the labels are too small and sometimes it's I don't get how you've built your experimental setup can you clarify this section? It's rarely catching biq mystake but really improves overall quality
