Making clear distinctions between the various types of addiction helps in the research for prevention and treatment of the particular types of addiction. Such distinctions are based on a multitude of factors, from both the biological side and the environmental side. Can behavioral responses to the warning messages be considered among these factors? My interest is particularly on the distinction between gambling addiction and other types of addictions, take for instance smoking. Studies have shown that the warning messages are generally ignored by both types of subjects. However, the post-message behavior is different for the two types: the smoker follows a sort of “I understand and agree with the health risks, but I simply cannot quit smoking, it is a biological necessity of mine”, while the gambles follows (among others) a sort of “I understand (or not) and (but) accept that I am subject to irrational beliefs and expectations and I might come to ruin, but what if I’ll get luck next time and hit the big jackpot? This happens around me for others, you cannot say that it is impossible for me.” Can researchers and practitioners for prevention/treatment gain something from this behavioral distinction in the vein of differentiating their interventions? Obviously, this also raises the issue of designing optimal warning messages regarding structure and content, but this is another topic.
