This is exactly how I felt when reading this! A reasonable hypothesis followed by some weak and vague experiments (how do you measure the creativity of drawings?). I'm sure many would accept the hypothesis alone (given some reasonable-sounding justification) without ever looking to see if the experiments truly validate the hypothesis. What bias is this called again? It's not Texas Sharpshooter is it? Maybe just poor science? Again, this is not to say the effect does not exist (I personally believe it does) - just that the conclusion does not follow from the evidence.
