when attention is drwan to the weapon and therefore may miss other important information.
When people were having conversation in a room and then a person was walking in. One group were faced with a person with a notepad and another were face with a person with a knife. Then people were asked to identify the person. Those who were faced with a person with a knife had a much lower accuracy. Therefore poeple's EWT may be dependant upon Weapon's Effect.
But this is not realistic - therefore lacks validity.
