You could still smoke indoors when I moved to Spain in 2009. Thankfully, it was banned in 2010 as part of an on-going anti-tobacco campaign that has since failed miserably. Fifteen years ago, 32% of people smoked. Today, 34% smoke. Somehow, the US has managed to get smoking rates down to 14%, and yet, even with a nationwide campaign, consumption here goes up. Why?

My guest on this week's podcast has spent much of her career studying and dissecting human habit formation and change. The reasons why you do what you do are not obvious and not even conscious, so changing them requires a deeper understanding of self.

Listen & Learn:

• How the US anti-smoking campaign was so successful
• Why the "5 a Day" healthy eating campaign flopped
• The small role that motivation plans in your habits
• What mechanisms are at play when habits are formed
• The roles of friction, cues, and beliefs in habit formation
