Analysts should be cautious because correlation alone does not imply causation. A significant correlation between variable A and B could mean that A predicts B, B predicts A, both are influenced by a third variable C, or the correlation is purely spurious. Without investigating the underlying linkages, using such correlations in predictive models can lead to incorrect conclusions. Additionally, a low or negligible correlation may still hide a strong nonlinear relationship, so analysts must explore further if they believe a genuine link exists.
