Skeet and Pescador's discussion points to the limitations of using individual observation to make conclusions, particularly conclusions with such
drastic consequences. Scientific observation is much needed and quantifying numbers of fish stock is vital as pointed out by SkipJack.
There are lots of studies that demonstrate how observer bias scews data. I recall my time as a lab assistant in a Behavioral Lab, each student had a
rat to train in their Skinner box. You know, rat hits lever, gets pellet, hits lever, gets another pellet etc. Well, after the students trained their
rats to press the heck out of the bar and then trained them to stop hitting the bar they took a final. One of the questions was: What was your rat
thinking as it went through this training. You should have seen the pages produced. The real answer to the question of course is: Who knows, rats
don't talk and we can't read their minds!"
