Air Date: February 5, 2026
Hosts: Alina Jasper (Head of Marketing) and Rob Demars (Chief Product Architect)

In this episode, Alina and Rob dive into the powerful and often surprising ways incidental emotions influence consumer economic decisions—a phenomenon demonstrated in the landmark “Heartstrings and Purse Strings” study. Using marketing psychology and real-world examples, they unpack how feelings like disgust and sadness (even when unrelated to shopping) can dramatically shift what people are willing to pay or accept for a product. The conversation highlights practical takeaways for marketers and reflects candidly on memorable ads that left lasting emotional impacts.

Key Discussion Points & Insights

The Study That Sparked It All: Heartstrings and Purse Strings

• Research Basis: Alina introduces the 2004 study, “Heartstrings and Purse Strings: Carryover Effects of Emotions on Economic Decisions” by Lerner, Small, and Lowenstein ([00:44]).
  • Study Design: 199 participants were exposed to clips meant to evoke neutrality, disgust, or sadness. Then, they completed an economic task assessing the value of a small object (highlighters), either as sellers or buyers ([02:24]).
  • Endowment Effect Principle: Normally, owners value their possessions more highly than buyers—the “endowment effect” ([02:31]).
• Rob’s Prediction:
  • Neutral = baseline behavior
  • Disgust = less open to buying
  • Sadness = more likely to “retail therapy” ([01:23]–[03:15])

Quote:
“If I’m having an insane day, like, I’m panic buying… I just realized I already owned half those things. Or if I’m like bummed out… I might be just doing a little browsing and emotional support.” – Rob ([01:23])

What the Research Found

1. Disgust Flattens Value

• Findings: Disgust led to lower valuations, eliminating the endowment effect. Both buyers and sellers valued the item less ([03:46]).
• Marketing Implication: Messaging or category cues that hint at disgust (even mild) can dampen willingness to pay. Relevant for categories like cleaning, medical products, or pest control.

2. Sadness Increases Openness to Change

• Findings: Sadness raised buying prices and lowered seller prices, leading to a reverse endowment effect. People wanted change—sellers let go for less, buyers paid more ([03:46]).
• Alina’s Insight: This may be why “sad ads” are compelling; sadness can open consumers to new solutions ([04:55]).

Quote:
“Sadness appears to motivate a desire for change, which can increase openness to new products or solutions…” – Alina ([05:25])

3. Emotional Nuance Beats “Positive” or “Negative”

• Key Point: Not all negative or positive emotions have the same effect—“disgust and sadness are both unpleasant… but they produce opposite economic behaviors” ([05:46]).
• Advice: Carefully differentiate which emotions are being evoked; emotion specificity matters more than general positivity/negativity.

Quote:
“Emotion specificity matters more than valiance. Negative emotions are not interchangeable.” – Alina ([05:44])

4. Neutral = Typical Economic Theory

• Findings: Neutral emotions yielded the standard endowment effect—owners valued items more than potential buyers ([03:46]).

Real-World Applications and Memorable Reflections

• Ad Examples Involving Disgust:
  • Rob recalls a skin cancer awareness ad where the actor removes his nose: “That was probably one of the most disgusting ads I’ve seen. But it was effective. …I wasn’t going, man, I want to go get skin cancer after…” ([06:25])
  • Alina references a Super Bowl commercial with “eyebrows flying off of people,” which she found disgusting ([07:16]).
  • Both agree that sometimes disgust is unintentional (“I don’t think their intent, though, was disgust… it might have just been us.” – Rob, [07:31]).
• Sadness & “Favorite Ads”:
  • Alina mentions how many favorite ads—like Google’s “Loretta”—are sad, possibly because they drive openness to change ([05:10]).
• On Annoyance and Marketing:
  • Rob: Wonders if “annoyance” would behave like other negative emotions, referencing catchy-yet-irksome jingles as both sticky and possibly effective ([08:19]).
  • Alina: Notes that a low level of annoyance may appear in high-performing ads, and it could be interesting to explore in future research ([08:47]).

Quote:
“Some of the most effective advertising can be a little bit annoying, but it works.” – Alina ([08:47])

Notable Quotes & Analogies

• On Emotional Weather:

  "Emotions are like the weather for your decisions. Disgust is a cold front that freezes value. …Sadness is a warm breeze pushing you to change things up. Same item, different emotional forecast, completely different price." – Rob ([06:03])

• On “Retail Therapy”:

  “The phrase ‘retail therapy’ proves that this is a thing for sure.” – Alina ([01:46])

• Emotional Nuance:

  “Negative emotions are not interchangeable. Disgust and sadness are both unpleasant feelings, but they produce opposite economic behaviors.” – Alina ([05:46])

Summary Takeaways

• Tiny, unrelated emotions can meaningfully change how consumers value products—sometimes negating core economic theories like the endowment effect.
• Marketers should carefully consider the specific emotional cues they evoke; “negative” isn’t a one-size-fits-all.
• Disgust suppresses value, while sadness appears to prime consumers to seek change and solutions.
• Future research (and marketing strategy) should embrace emotional nuance—potentially even leveraging “annoyance” for sticky, memorable messaging.

Nerd Alert. Learning is important, right?

[B]

Yes, exactly. What a bunch of nerds.

[A]

Nerd alert. That's right.

[B]

Marketing Architects. Hello and welcome to the Marketing Architects, a research first podcast dedicated to answering your toughest marketing questions. I'm Alina Jasper. I run the marketing team here at Marketing Architects. And I'm joined by my co host, Rob demars, the chief product architect of misfits and machines.

[A]

Hello.

[B]

Hello. We're back with your weekly Nerd Alert. Every week, I'll take a deep dive into academic marketing research and translate its complex ideas and into simple, understandable language for Rob and of course, for all of you. Are you ready to nerd out, Rob?

[A]

I don't know what it is about today, but I am feeling bold, optimistic, and wildly under qualified. So let's do this.

[B]

Perfect. Let's get into it. Today we're looking at a study I think marketers will genuinely appreciate because it examines how emotions, even emotions that have nothing to do with the decision at hand, influence what people are willing to spend. The paper has a fun title. It's Heartstrings and Purse Strings Carryover Effects of Emotions on Economic Decisions. This is by Jennifer Lerner, Deborah Small, and George Lowenstein. It was published in 2004 in Psychological Science. The findings are striking, and they challenge some core assumptions about how people assign value. But before we get too far, Rob, do you ever notice yourself maybe shopping differently depending on the kind of day that you're having?

[A]

Of course, if I'm having an insane day, like, I'm panic buying, oh, yeah, I need that, I need that. Oh, great, I'm buying that. And then I just realized I already owned half those things. Or if I'm like bummed out and I'm just like, man, I could use a little serotonin, I might be just doing a little browsing and emotional support, not just buying products and buying happiness. So, yeah, definitely.

[B]

I think the phrase retail therapy proves that this is a thing for sure emotion. Yeah, it could change how we make decisions for sure when we're shopping. So this study suggests that our emotions shape economic decisions far more than we might assume. Even small, momentary feelings can meaningfully shift what people are willing to buy or sell. So here's what the researchers did. They brought in 199 participants and randomly assigned them to one of three emotions, neutral, disgust, and sadness. To reduce those emotions, they showed people emotionally charged film clips that represented each of the three emotions. This is so fun. I want to be a part of this study.

[A]

I want to know what these film clips Are. I don't know, like what was discussed, you know, what do they show people?

[B]

I cry at any. I'm a sympathetic crier, so just show me somebody crying. I'll do it. So immediately afterwards, the participants completed what appeared to be an unrelated economic task. This is kind of a classic endowment effect exercise. Half the group were given a small object, a set of highlighters, and asked how much they would sell it for. The other half, who did not own the object, stated how much they would pay to acquire it. Under normal conditions, people value items they already own more highly. Right. Than identical items they do not own, which we've probably. I don't know if we talked about that on the show, but I've heard of it. Yeah, it's like they call it the endowment effect. Rob, before I tell you what happened in the study, what would you expect these emotions to do? You know, neutrality, disgust and. And sadness. What would you. How would you predict they'd change things?

[A]

I feel like neutral is just like the word, right? You're kind of on autopilot and you're just doing your thing and no major pull one way or the other. I know for me personally, like, if disgust, if I'm like just feeling in that mood, I'm probably not real open to buying things or excited to. To really listen to ideas. Sadness, like I talked about earlier, that's like opening up Amazon and Amazon whispering, you know, I'm here to help, like, come and buy.

[B]

You're like, really spot on with what they found. So we'll start with disgust. Like you said, that reduced valuations across the board. So participants that were assigned that feeling of disgust, they did not want to pay more whether they were selling or buying. Like they were assigning lower values across the board. So ownership didn't matter if they felt like, oh, this is my own thing. The endowment effect essentially disappeared. Sadness produced a completely different shift. So you're right, people were going to raise their buying prices if they were in the sadness group. But also sellers were willing to lower their selling prices, which is interesting. So there was this reverse endowment effect. Buyers are willing to pay more than what sellers required. So this emotional site seemed to motivated a desire for change, letting go of what one has and seeking something new. Then, like you said, neutral participants behaved as expected in the absence of strong emotion. The traditional endowment effect held sellers value the item more than buyers, just as standard economic theory predicts. So what do we do with all this? First, incidental emotions matter. Your audience's emotional state, even when the source has Nothing to do with your brand can meaningfully influence how they assign value. This is easy to overlook, but the data shows the effect is substantial. Second, disgust suppresses value. When an environment, a category, or a message evokes even mild disgust, it can reduce willingness to pay. This makes me think of. There have been some super bowl commercials that are truly disgusting. This makes me think of stuff like that. So if you're in a category like cleaning, medical products or pest control, this is especially important to consider when you're developing your creative. Third, sadness increases acquisition. Sadness appears to motivate a desire for change, which can increase openness to new products or solutions for categories positioned around improvement or relief. This emotional pathway is relevant, though of course you should approach it thoughtfully. This study made me think about how my favorite ad ever is Google's Loretta ad. I feel like a lot of my favorite ads are sad. Like, maybe this is part of the reason why. Like, that kind of works when you're selling something. Fourth, emotion specificity matters more than valiance. So what does that mean? Negative emotions are not interchangeable. Disgust and sadness are both unpleasant feelings, but they produce opposite economic behaviors. So if you're trying to use emotions to plan around your advertising, be careful because not all negative emotions are the same and not all positive emotions are the same. So the implication is that emotional nuance matters a lot. All right, time for a Rob, Emotions are like the weather for your decisions. Disgust is a cold front that freezes value. Nothing feels worth much. So sadness is a warm breeze pushing you to change things up. Say an item, different emotional forecast, completely different price. All right, Rob, Kind of a short but sweet one it is.

[A]

I'm trying to think of an ad off the top of my head that used disgust. Like, just. I'm trying to, like, rack my brain. Do you have any that are top of mind? Because I'm. I'm just. Maybe that's the point. I repelled them and I didn't want to see the message, but I can't. I can't think of it. Except for maybe in the philanthropic space where I remember this. A long time ago, there was an ad for the Skin Cancer association where this guy was talking about how he used to love to get a good burn when he was a kid and now he regretted it. And in the commercial, he actually pulls his nose off. Oh, and that was probably one of the most disgusting ads I've seen. But it was effective. You know, in that case, I wasn't going, man, I want to go get skin cancer after. You know, I was definitely did its job.

[B]

It might depend on what disgust means for you. Like, I personally, during the super bowl, the commercial where the eyebrows were flying off of people.

[A]

Yes, that was.

[B]

I found that a little gross.

[A]

Literally wanted to throw up.

[B]

Yeah.

[A]

I don't think their intent, though, was discussed. I don't think they were going, this is a lever that we're gonna switch.

[B]

No, it might have just been us. I don't know. I just, I found.

[A]

Oh, I was a hundred percent. I mean, 110%.

[B]

You know what else I found? You probably won't agree with this. When they turned seal into a seal, I found that kind of gross too.

[A]

Yeah, yeah, I can see that. I can see that.

[B]

Something about it that's a little like a little icky. But yeah, a fun study. It makes me think about too. Like this. They're just looking at these three emotions. I don't know if you call neutrality an emotion, but it'd be interesting to look at different ones. I know there's further studies on that. This was a while ago, but kind of fun to see the foundation for now there's a lot more work on. Yeah. Specific emotions and how well they do for your advertising. But it's fun to go back to something that was foundational.

[A]

So the one I would love to see a study on is annoyance. Because there's two sides to that one, Right? Annoyance. You'd go, well, that's a negative thing. I don't want to hear it again. But at the same time, save big money at Menards is kind of annoying to hear sung to you over and over. But it's sung to you over and over in your head as well when you're driving down the road because it annoyed you at some point and stuck there.

[B]

I feel like I've read research that includes that type of emotion, like being annoyed or irked a little bit. And I think that it does appear in high performing ads. It probably depends on the level. That's what I'd have to guess. But that could be interesting to cover too, because you're right. Some of the most effective advertising can be a little bit annoying, but it works.

[A]

Yeah.
