Anyone who has ever played Japanese Reach Mahjong can tell you with some certainty as to the astuteness of the point made.
Ignoring any aspect of the other player's discards (or, more to the point, telling signs emanating from any of the players in a company with the power to reject your product) is a certain path to failure.
When you have 3 other skilled players (or X number of competitors) - all of whom can deal triple damage to you if you aren't careful - you learn to avoid losing.
