Camelia Kuhnen, then of Stanford with her Stanford colleague Brian Knutson and Vanderbilt’s Gregory Samanez-Larkin posit a small but meaningful genetic basis to risk-averse financial investing, providing a biological basis for findings that women hedge fund managers outperformed male counterparts.

Volunteers with two short serotonin transporter genes (5-HTTLPR) reported that they tend to worry, and this pattern was associated with chosing less risky investment choices.

“Short allele carriers” also showed higher levels of the personality trait “neuroticism,” but no significant difference in cognitive skills, education, or financial status.
Kuhnen estimates that less than 30 percent of variance in risk-taking is attributable to short 5-HTTLPR, and the remaining difference is derived from experience, culture, education, and social environment.

Kuhnen and Knutson reported the neural basis of financial risk taking using event-related fMRI.
They observed that the nucleus accumbens was activated before volunteers made risky choices and made risk-seeking mistakes.
In contrast, they found that the anterior insula was activated before risk-free choices and risk-aversion mistakes.

They proposed that different neural circuits are associated with differing emotions as volunteers anticipate gain or loss associated with financial choices.
This emotional activation “signature” can lead to specific investment choices, favoring or avoiding risk, and may lead to investing mistakes.

In unpublished research, Kuhnen found that short-allele carriers showed increased anxiety before making a decision in a trial-and-error risk discovery task, but reacted no differently than long-allele carriers when they observed a negative outcome.

She noted that volunteers differ in how they anticipate and react to a potential decision before they make it rather that in their reactions to actual outcomes of investment decisions.

Joan Chiao

Kuhnen, now at Northwestern collaborated with Northwestern colleague Joan Chiao to investigate the impact of both the 5-HTTLPR gene and the DRD4, gene, which regulates dopamine transmission.
These genes and their related neurotransmitters have been linked to emotional behavior, anxiety and addiction.

Their research replicated Kuhnen’s earlier finding that individuals with two short 5-HTTLPR alleles take 28% less risk than people with other combinations, and they demonstrated that the double DRD4 7 allele carriers took 25% more risk than people with other combinations.
They conclude that serotonin is associated with risk-averse investment choices, whereas dopamine is associated with riskier choices.

Kuhnen and Chiao argue that risky investment behavior shares commonalities with other risky behaviors like drug use, gambling, unsafe sex, dangerous physical and social pursuits, and more.

Why Organizations Care about Employee “Happiness”

“Command-and-control” managers of the past might have scoffed at current business research on happiness.
Under their spans-of-control, employees ought to have been happy to have a job from which they derived an income.
This view has been supplanted by widespread recognition that desirable outcomes like innovative problem solving, flexible decision making, and workplace productivity are associated with employees’ positive mood.

GallupResearch by the Gallup Organization offers further justification in its finding that disgruntled employees disengage and cost the American economy up to $350 billion a year in lost productivity.

Therefore, organizations can increase financial performance by improving operational efficiency in the many processes involving people.

Sigal Barsade

Sigal Barsade

Sigal Barsade of the Wharton School of Business contributed to the investigation of happiness’s impact on organizational productivity.
She found that positive moods prompt “more flexible decision-making, wider search behavior and greater analytic precision,” which enable the organization to take considered risks.

Jennifer Aaker

Jennifer Aaker

On the other coast, Jennifer Aaker, award-winning professor at Stanford Graduate School of Business, links workplace happiness and a sense of meaning.

She asserts that having a meaningful impact on the world is a strong predictor of happiness and that it’s possible to cultivate mindfulness and awareness of meaning in work and personal activities.
This cultivated awareness, she said, influences people’s subjective well-being and may positively affect that of others in a contagion effect.

Jonathan Haidt

Jonathan Haidt

New York University’s Jonathan Haidt, a psychologist in the Stern School of Business, takes a more philosophical view of happiness.
He redefines “wisdom” – other might say “leadership” or “self-management” – as the ability to adapt, shape the environment, and know when to move to new environments.

His moral and ethical framework includes high-level philosophical “virtues” associated with a sense of well-being and shared across cultures:

  • Courage
  • Humanity
  • Justice
  • Temperance
  • Transcendence

The Happiness HypothesisHaidt’s book, The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom , specified contributors to well-being:

  • Strong marriages
  • Physical touch
  • Meaningful relationships
  • Religious affiliation
  • Autonomy
  • Meaningful engagement in work
  • Contributing to a community through voluntary effort

Engineering organizations analyze issues according to “Is-Is Not.
Using this approach, Jonathan Haidt’s research offered some surprising happiness detractors or “is-nots”:

  • Persistent noise
  • Long commutes
  • Lack of situational and person control
  • Shame
  • Dysfunctional relationships
Matthias Mehl

Matthias Mehl

Matthias Mehl of the University of Arizona offered an additional contributor to happiness: Interpersonal dialog.
He found that volunteers who engaged in a meaningful conversation create shared meaning, strengthened their connections, and reported feeling happy.

Jennifer Michael Hecht

Jennifer Michael Hecht

Jennifer Michael Hecht’s The Happiness Myth, offers a framework for types and levels of happiness:

  • Good day, awareness, savoring, and gratitude for the fortunate conditions of one’s life
  • Good life, engaging in meaningful and challenging tasks that help provide a material quality of life and doing one’s best in any endeavor
  • Peak, choosing experiences that inspire awe and a sense of the eternal, connect to families and communities.

The Happiness MythShe cites familiar recommendations to:

  • Cultivate self-knowledge
  • Develop a clear view of one’s worth
  • Moderate desires
  • Appreciate mortality and time limits
  • Try new things
  • Increase involvement with others and the community.

Organizational policies can contribute to employees’ sense of well-being through establishing:

  • Opportunities for career movement and development
  • Regular acknowledgement and praise for a job well done
  • Focus on well-being as individuals through health and work/life integration programs

The payoffs to organizations include increased productivity, innovation and engagement.

“Productive Pause”, Intuition for Better Decisions

Everyday wisdom offers familiar advice to curtail impulsivity through slowing down and reflecting:

  • “Go slow to go fast”
  • “Sleep on it”
  • “Wait before sending an emotional email”
  • “Count to 10, think again”
Frank Partnoy

Frank Partnoy

Former investment banker and lawyer Frank Partnoy’s Wait: The Art and Science of Delay provides empirical evidence on the value of delay to increase the quality of decisions and performance across investment, sports, comedy, and other disciplines.Wait

Creativity experts have demonstrated the importance of an “incubation period” in developing innovative solutions, and Partnoy suggests that similar principles provide and advantage: gathering maximum information in uncertain situations, by executing decisions and performance close to the last opportunity.

University of San Diego’s Partnoy recommends a three step approach to decision-making:

1) Determine the maximum time available to gather information and take the decision
2) Consider, reflect, “incubate” on the information as long as possible
3) Act quickly at the last possible moment

Malcolm Gladwell

Malcolm Gladwell

His approach could be summarized by referring to Malcolm Gladwell’s best-seller, Blink: The Power of Thinking Without Thinking : “Don’t just blink but think.”

Nalini Ambady

Nalini Ambady

Gladwell argues that people with expert experience and insight are often skilled at using ‘adaptive unconscious’ intuition to “thin-slice” subtle cues to filter relevant information from “noise,” a concept based on Nalini Ambady and Robert Rosenthal’s research at Harvard.

Justin Albrechtsen

Christian Meissner

Christian Meissner

Research by Justin Albrechtsen, Christian Meissner, and Kyle Susa  of University of Texas at El Paso demonstrated “thin-slicing” when they found that intuitive processing can lead to more accurate judgments of deception when compared with deliberative processing.

Kyle Susa

Kyle Susa

Gladwell and these researchers acknowledge that non-experts, and even experts, can be make erroneous decisions due to bias and prejudice that comes from automatic thinking and habitual cognitive heuristics like the halo effect.

Gerard Hodgkinson

Gerard Hodgkinson

Gerard Hodgkinson of Leeds University found that biased intuitive judgment may be mitigated by “devil’s advocacy” and applying analytical tools like multi-attribute decision analysis and root cause analysis.

He suggests that informed intuition or ‘intelligent-unconscious’ results from subconscious information storage, processing and retrieval, and has conducted several empirical studies to evaluate its mechanisms applied to developing business strategies.

Intuitive judgment was positively correlated with quality and speed of decisions, organizational financial and non-financial performance in at least five studies.

Hodgkinson’s team summarized recent advances in neuroscience, including functional magnetic resonance imaging (fMRI) studies to explain complementary intuitive and analytical approaches to decision making  instead of the overly-simplified notion of left brain vs right brain processing  strengths.

He synthesized intuition attributes:

  • Instantaneous insight after incubation period
  • Subjective judgments
  • Based on experience, tacit knowledge, “knowing without knowing
  • Arise through rapid, non-conscious holistic associations
  • Affectively-charged: “feels right”, experienced as ‘‘inklings’’ or ‘‘glimmerings’’
  • Lacking verbalization or conscious awareness of problem solving.

Cognitive neuroscientists have differentiated intuition from instinct and insight using functional magnetic resonance imaging (fMRI) techniques.

Instinct refers to hardwired, autonomous reflex actions, whereas insight involves recognizing and articulating a problem’s structure, and may follow from intuition.

Hodgkinson’s research suggests that intuition can be enhanced by increasing:

  • Expertise (“prepared mind” or ‘‘deep smarts’’)
  • Self-awareness (feeling and cognitive style)
  • Reflection
Akio Morita

Akio Morita

His team’s research supports an assertion by Akio Morita, co-founder of Sony and driving force behind its successful Sony Walkman, that ‘‘creativity requires something more than the processing of information. It requires human thought, spontaneous intuition and a lot of courage.’’

Consider All Your Options at Once, Be Happier with Choices: Minimize “Quest for the Best” Bias

Sheena Iyengar

Sheena Iyengar

Columbia Business School professor Sheena Iyengar, Cassie Mogilner of University of Pennsylvania’s Wharton School, and Baba Shiv of Stanford’s Graduate School of Business collaborated to assess the relative satisfaction and commitment to “sequential choices,” as in “love marriages,” compared with “simultaneous choices”, like arranged marriages.

Iyengar’s earlier research revealed that more choices available at one time are associated with reduced satisfaction.
The Art of ChoosingTo evaluate satisfaction with simultaneous vs sequential choosing, Iyengar, Shiv, and Mogilner studied volunteers’ satisfaction and commitment to choices of wine, chocolate, and nail polish colors.
Results, forthcoming in the Journal of Consumer Research, found thatsimultaneous” choosers were more satisfied and committed to their decisions than “sequential” choosers.

Cassie Moligner

In the chocolate experiment, participants considered detailed descriptions of fine chocolates (“dark chocolate ganache with black tea and hints of citrus and vanilla”), and chose which they wanted to taste.
The “simultaneous” group saw the entire list, whereas the “sequential” group saw one choice at a time.

After they selected and tasted the chocolate, participants rated their satisfaction with their choice.
Verdict? “Simultaneous” choosers were more satisfied with their choices than “sequential” choosers.

Baba Shiv

When participants had an opportunity to switch to a different but randomly-selected chocolate, more “sequential” choosers took this option, though they had little information about the choice.
However, when “sequential” choosers were permitted to choose an option they’d already considered, they were less committed to their choice.

The researchers suggest that “sequential” choosers may have regretted forgoing options they didn’t select, and hoped that a future option would be better.

Shiv summarized the dilemma of the “sequential” chooser (or serial dater, serial monogamist): Hope and regret prompt people to move to the next option even though the next option could be worse.
In contrast, “simultaneous” choosers are aware of available options at a point in time, so may spend less time in regret and hope.

Retailers, daters, venture capitalists, hiring managers, house purchasers, and job candidates benefit from presenting and evaluating all choices at one time.

However, simultaneous choice may not be possible, and to avoid the “bias of the eternal quest for the best,” Shiv suggests “mentally converting sequential choices into “quasi-simultaneous” choices by recalling situations when you were happy with you choice, and when you regretted your choices.”

Though an imperfect heuristic, quasi-simultaneous choice may may provide instructive clues to the elements of a satisfying decision.

Human Decision Biases Modeled with Automatons

Yuval Salant

Yuval Salant

Yuval Salant of Northwestern University’s Kellogg School of Management, notes that research by psychologists and behavioral economists established that humans exhibit predictable biases in making decisions.

He created an algorithm-based mathematical model of how a machine would make choices with limited information.
Some automatons make the same type of predictable errors as humans, including the “primacy” effect (choosing one of the first items on a list) or the “recency” effect (selecting the last item on a list).

One of Salant’s automatons is based the decision-making strategy known as “satisficing”, or establishing in advance the criteria an option must fulfill to be selected.
This type of decision-making may pertain in selecting a meal, a residence, vehicle, vacation, or mate.

These three decision-making tendencies might be considered short-cuts, or heuristics, to avoid the exhaustive task of thoroughly analyzing every possible option.

As a result, computer scientists surmise that this type of “rational” (thorough) decision making does not scale for large problems, due to limitations of processing power and memory.
The same may be true for human decision-making in light of limitations to “working memory” (correlated with IQ), not to mention inevitable time constraints.

Salant’s most human-like automaton is a “history-dependent satisficer,” which may remember previously-considered and may modify its decision criteria based on available options.

He pointed to examples that support the decision biases he identified: people are more likely to vote for candidates who appear first on a ballot, to order one of the first items on a menu, to click on options at the top of a computer screen (such as an airline or hotel option).

Overcoming Decision Bias: Allure of “Availability Heuristic”, “Primacy Effect”

Dana Carney

Dana Carney of Berkeley’s Haas School of Business and Mahzarin Banaji of Harvard University investigated whether people prefer the first option they receive in their paper, “First is Best”.

Olympics gymnastic competitors are aware of this phenomenon, and typically prefer to perform first, to “set the standard” against which other competitors must excel.
Volunteers in one experience were shown pictures of two violent criminals and then asked which one deserved parole.

Mahzarin Banaji

Mahzarin Banaji

Most favored the first mug shot they viewed, no matter the order of viewing.
Similarly, 68% of respondents at a railway station in Boston preferred the first stick of gum they were offered, and volunteers preferred to buy a car from the first salesperson they met.
This is one reason that the first advertisement break on television costs 10-15% more than the second, according to Jonathan Allan, sales director at British broadcaster Channel 4.

Carney and Banaji concluded that people “consistently” the first choice if they have time limits or are distracted, and that this primacy effect is even more important online, because few people scroll through dozens of pages of search results.
Google page rankings, and dating sites such as Badoo, are aware of this trend, and offer enhancements to position results in a more eye-catching location.

Awareness of the human cognitive short-cuts that bias decision making can mitigate their effects.

Is Career “Planning” Actually Career “Improvisation”?

Kathleen Eisenhardt

Kathleen Eisenhardt and Behnam Tabrizi’s study of product innovation in the global computer industry in Administrative Science Quarterly, concludes that planning is most suited to circumstances relatively certain circumstances in which processes and decisions are typically linear.

In contrast, they assert that under frequently-changing or uncertain conditions with many iterative modifications, improvisation coupled with frequent testing is a more appropriate strategy.

Behnam Tabrizi

Many examinations of contemporary shirts in global economic and business circumstances suggest that the context of current career “planning” occurs under rapidly-shifting conditions more appropriate for an “agile” strategy.

As a result, it is increasingly difficult to meaningfully respond to the frequently-asked interview question: “What are your career plans for the next five years?”

It may be appropriate to refer to iterative exploration, rapid prototyping/experimentation, and testing characteristic of agile development in the VUCA (volatile, uncertain, complex, ambiguous) world.
