Among our five senses, the sense of smell is the oldest sense. People can detect at least one trillion distinct scents and research has shown that women have a better sense of smell than men.
One interesting study published in the journal Psychological Science entitled “Chemosignals Communicate Human Emotions” suggest that people can smell feelings of fear and disgust through sweat, and then they can experience the same emotions.
The 2012 study conducted at Utrecht University in the Netherlands collected sweat from men as they watched movies that elicited feelings of fear and disgust. To remain odor-neutral, they asked the men to use scent-free products, quit smoking and eliminate alcohol consumption.
Women participants they completed visual search tests, which unknowingly smelling the sweaty samples. They eye movement and facial expressions were recorded and examined.
Researchers found that women who smelled the “fear sweat” opened their eyes widely in a fearful expression, and the women who smelled the “disgust sweat” also displayed facial expressions of disgust.
The researchers suggest that these findings underline the neglected social relevance of chemosignals in regulating communicative correspondence outside of conscious access.
I’ve traveled a lot this year and have a lot more trips coming up. If my travel schedule plays out I’ll have been on the road half of the weeks this year and spent at least 50 nights in hotels. Think about that– 10 weeks away from my family! Some days have entailed hitting the road by 4 a.m. to catch early morning flights and arriving home close to midnight. If you travel you know if can be tiring!Last month, as I waited to catch an evening flight home I got a text from my daughter, Abigail, asking if I wanted to get some ice cream at Graeter’s when I landed because she wanted to tell me about her first days of college. Despite being tired I agreed because I don’t view such times as a sacrifice; rather it was an investment in her and our relationship.As we waited in line I tried to decide what flavor I was in the mood for and whether I’d go with a single scoop or a double. If you’ve been to Graeter’s you know the ice cream is great but you pay a premium for it! 
As I looked at the menu I saw a single scoop cone was $2.95 and a double was $4.25. I thought, “I just bought a half gallon of really good Homemade ice cream for just over $5,” so I was reluctant to get two scoops at that price. The other thought that raced through my head was, “That’s almost twice as much.” When you do the math, you know it’s not twice as much, but my mind quickly registered the $2.95 and $4.25 as $2 vs. $4 because those are the numbers each price started with.Something else that came into play as I decided what to do was the fact that I was still a little full from dinner a few hours ago. I decided to skip the cone to save a few calories so I asked for a single scoop in a cup. The server said, “Would you like a second scoop for just 50 cents more?” I recall thinking, “For 50 cents why not, that’s a good deal?” because in my mind the option of going from one to two scoops was twice as much ice cream but not at double the price.As it turns out, the single scoop in a cup was $3.75 and two scoops were $4.25…the same prince as the two scoops in a cone that I’d just decided to pass on! It was only a 50-cent difference but in the end I got two scoops…no cone…and paid the same amount I’d mentally rejected moments before!I read lots of books on the subject of persuasion, pricing, etc., and yet I ended up in the very place I was initially trying to avoid. Before you chuckle, I can assure you I could probably spot similar inconsistencies in some of your decision-making.So what happened to me? My focus shifted from “two scoops for nearly double the price” to “a second scoop for just 50 cents more” when in the end, the price was $4.25 in each case!When we make decisions we rarely do so in a vacuum. To assess a “deal,” we’re always making comparisons to other things. My first thought was two scoops for about the same price as a box of ice cream is not a good deal. However, knowing the first scoop was pretty expensive, getting a second scoop for just 50 cents more seemed like a great deal. My mistake was that I didn’t pay close attention to the price of a single scoop in a cone vs. the price of one scoop in a cup. I mistakenly assumed getting ice cream in a cup would be less expensive, certainly not more, because I couldn’t eat the cup.So here’s the “scoop” next time you’re faced with a similar decision.Try to remove your emotions from the decision. Many behavioral economics studies show people are emotional creatures that occasionally make rational decisions (i.e., We have five TVs but I want a 66-inch flat screen!).Recognize you’re always making comparisons to other things. Make sure you’re comparing to the right thing and don’t just look for something that will confirm what you emotionally want (i.e., I know we don’t need another television but it’s 50% off!).Take a moment to consider the value of the thing you’re considering regardless of what you’re comparing to. Value is subjective but oftentimes we ascribe too much value to things we believe will make us happier or more fulfilled (i.e., What will the 66-inch screen, even if on sale, really add to your life?).Follow these simple steps and you’ll probably make better decisions; the kinds you look back on with pride, not regret.
