An interpretation that is biased is not necessarily a bad thing; it can help speed up the work involved in an elucidation of an unknown. On the flipside, an incorrect interpretation based on a bias can really hamper an elucidation.
From the 1H -13C HMQC spectrum, the two correlations aligned with the carbon signal at 126 ppm indicates an initial assignment of a simple CH2 group. However, a second scenario is possible, that is, two CH groups where the two carbon signals coincide. Armed with this information, the chances of an unsuccessful elucidation are greatly reduced.
