Choice overload hypothesisHaving an extensive number of options to choose from

appears to have more of a negative effect than intended or expected- Feelings of dissatisfaction, regret, frustration have been shown to result from choosing from an over-extensive set of items

Individuals faced with over-extensive choice tend to defer decision, search for new alternatives, choose the default option, or simply opt not to choose (Dhar,1997)

As the complexity of making choices increases (resulting from an increase in options to choose from), people tend to rely on simple heuristics to mediate their decision-making process (Payne, 1982) and integrate less information than if faced with less options (Timmermans, 1993)

Is less always more? Testing the limits of the choice paradox

This paper presents strong arguments for and against the choice overload hypothesis.

However these arguments are not evenly weighted, which may influence the readers perception of the argument.

It addresses issues relevant to real life settings and therefore has great implications for the world of marketing.

When Choice is Demotivating: Can One Desire Too Much of a Good Thing? -Sheena S. Iyengar and Mark R. Lepper (2000)Study 1: Choosing Wilkins & Sons

JamMethod Two tasting booths set up in

grocery store: one offering 6 choices of jam; the other offering a choice of 24

Consumers observed for initial attractiveness to each number of alternatives and subsequent purchasing behaviour

Results Initial Attractiveness to Selections

- 60% of customers in store stopped at the extensive-choice of jams- 40% of customers in store stopped at the limited-choice of jams

Study 3: Godiva Chocolate TastingMethod 3 conditions: limited-choice (from 6 chocolates),

extensive-choice (30) and assigned choice Participants completed a questionnaire regarding

the chocolate tasting experience and upon completion were given the opportunity to redeem either £5 cash or a £5 box Godiva chocolates

Results Extensive-choice participants described the choice

of samples as “too many”. Extensive-choice participants reported their choice

process as being more enjoyable yet more difficult and frustrating

No differences between confidence of being satisfied by the chocolate selected nor how informed the participants felt regarding their choice

No difference between the two conditions concerning whether participants satisficed or optimised on their choices

Limited-choice participants were more satisfied and less regretful about their choice than those in the two alternative conditions; however, participants who had the freedom to choose were more satisfied overall than those with no choice on their sample• Subsequent purchasing behaviourSubsequent purchasing behaviour- 48% of participants in the limited-choice condition chose chocolates over - 48% of participants in the limited-choice condition chose chocolates over money as compensation compared to only 12% in the extensive-choice condition money as compensation compared to only 12% in the extensive-choice condition and 10% in the no-choice conditionand 10% in the no-choice condition

Discussion of findings It appears that too much choice can in fact be a negative factor in

choosing and purchasing items Whilst a vast array of choices may initially seem desirable, they

often have an eventual detrimental effect on human motivation The results of these studies show that human motivation is much

improved when the choices are restricted A purchase of Wilkins & Sons jam was much more likely to be

made when the options remained limited Essays were more likely to be written and of a higher quality

when the choice of topics was small A decision to invest in a box of Godiva chocolates was more

likely when a sample chocolate was chosen from a smaller selection

Contrastingly, study 3 provides evidence showing that it is important for consumers to have some choice, as those who sampled chocolates previously chosen for them were least likely to take home a box of chocolates and reported being least satisfied with their sample

The studies and their resulting implications are particularly relevant and useful for the marketing world

Page 10: Is less always more? Testing the limits of the choice paradox

Points of considerationWas the study design

appropriate for the research question?2/3 studies used a natural observation design, therefore have ecological validity. However the 3rd study was carried out in a lab setting and therefore cannot be generalised to a wider population

Does the study add anything new?Yes. This paper provides new data and a new theory of choice paradox

Is the study question relevant?

"As consumer choice grows consumers are feeling overwhelmed and it is starting to have a negative effect on lives"

Implications

If too much choice leads to no choice then maybe supermarkets should reduce the number of items stocked to increase sales?

Page 11: Is less always more? Testing the limits of the choice paradox

What moderates the ‘too much choice’ effect? - B. Scheibehenne, R. Greifeneder & P.M. Todd (2009)Study 1: RestaurantMethod Participants were entered into a competition to win either €30 or €40 worth

of restaurant coupons Upon winning, participants were given the choice of either prize – if they

chose the latter option, they were required to choose a restaurant to dine at from a list of either 5 or 30

Participants rated how difficult their choice was and whether they thought the range of restaurants was large or small

Results No difference between choice of coupon over cash for participants selecting

from an extensive list than from a limited list (35% vs. 30%) Participants in the extensive-choice condition had slightly more difficulty in

making a choice than those in the limited-choice condition The variety of the extensive-choice condition was perceived as larger than

that of the limited-choice condition. (This shows that the size of choices available was not subjective)

Conclusion No supporting evidence for the choice overload hypothesis The effect is not seen regardless of the fact that more items make a more

difficult choice

Page 12: Is less always more? Testing the limits of the choice paradox

What moderates the ‘too much choice effect’? - B. Scheibehenne, R. Greifeneder & P.M. Todd (2009)Study 2: Charity study (three collated mini studies)Method Participants took part in an unrelated laboratory study. Upon completion, they were

given €1 and were offered the choice to keep it for themselves or donate it to charity Before deciding what to do with the money, they were presented with a list of either

popular or unknown charities of varying sizes Participants were either required to justify their decision with a written statement or

make no justification at allResults ‘Too much choice’ effect was not evoked from:

- a decrease in number of choices in limited-condition- a increase in number of choices in extensive-condition- the familiarity of the charity- cultural differences

Justifications contained more characters when choosing from a larger set of charitiesConclusion Only the requirement to justify one’s decision did evoke the “too much choice” effect

due to the choice being more difficult

Page 13: Is less always more? Testing the limits of the choice paradox

Discussion of findingsThis paper discredits the ‘too much choice’

effect as it is not observed in any of the studies except when a justification of the choice is required

At least, the effect is less robust than Iyengar and Lepper (2000) suggest

Page 14: Is less always more? Testing the limits of the choice paradox

A new paradigm?Factors that may be important in such a new paradigm:

Assortment structure – Organisation, number and distribution of assortment affects ease with which information can be retrieved, quality of the decision made and motivation to purchase

Decision strategy – The too much choice effect may be a result of failure to adapt ones decision strategy to the current situation

Decision avoidance – Explore possible different explanations for why people avoid making a decision E.G. keeping the status quo

Page 15: Is less always more? Testing the limits of the choice paradox

Points of considerationWas the study design

appropriate for the research question?The design is appropriate for the issue at hand, however the lab settings still restricts its generalisation to the wider population

Does the study add anything new?It builds upon previous research, aiming to establish in what conditions the too much choice effect occurs

Did the study methods address the most important potential sources of bias?Yes. Factors that may bias the data were controlled for e.g. The participants remained anonymous, ruling out demand choice effects

ImplicationsThe researchers suggest that further research needs to be undertaken to explore a new paradigm in which the too much choice effect occurs reliably

Page 16: Is less always more? Testing the limits of the choice paradox

Why can no-one agree?

It seems that the ‘too much choice’ effect does influence consumer behaviour, but not in all circumstances

A meta analysis by Scheibehenne et al’s (2009) highlights that the ‘too much choice’ effect may depend on an interaction between several factors that all have to hold before it is elicited

Page 17: Is less always more? Testing the limits of the choice paradox

Why can no-one agree?Individual differencesEveryone’s decision making processes are

different: A Satisficer is someone who searches and

selects something that is ‘good enough’ Maximisers aim for the best possible option

in a given set and search all options to find itSchwartz et al (2002) proposed that the ‘too

much choice’ effect is more likely to affect maximisers, because finding the best option gets harder as the set size increases

Page 18: Is less always more? Testing the limits of the choice paradox

Why can no-one agree?

Familiarity

Some items in a given choice assortment may be familiar to some but not others, creating a choice bias unknown to the researcher

Lack of familiarity with, or lack of prior preferences for the items in the choice assortment will result in the choosers not being able to rely merely on selecting something that matches their own preferences (Iyengar and Lepper 2000)

Page 19: Is less always more? Testing the limits of the choice paradox

How to cope with all this choice…“Our research shows that consumers are finding their own solutions to cope with this increasing burden of choice. Choosing well known and trusted brands is one, but some people are starting to employ less obvious strategies like buying only organic products or shopping only on a Friday when the supermarket shelves are less full.”

Michael WillmottMichael Willmott

Page 20: Is less always more? Testing the limits of the choice paradox

How to cope with all this choice… Lighten up when selecting your bread or milk- don’t take the

everyday task too seriously- it’s not the end of the world if you buy bread with oats in by mistake!

Opt for small shops that offer less choice- big potatoes vs. small potatoes!

If you are confused, ASK FOR HELP! If you know you just want salted butter then ask for advice rather than ending up with low fat, diary free, gluten free, organic butter

Save those big decision moments for things that warrant the potential stress, like...

Choose when to choose- only start thinking about when to decide what cheese to buy when you are in the cheese aisle...not hours before

Enjoy what you have, don’t waste your time worrying about what you don’t have

Be a satisficer (accept a ‘good enough’ option) not a maximiser (always wanting ‘the best’ option)

Page 21: Is less always more? Testing the limits of the choice paradox

Conclusion There are two completely opposing views regarding the existence of

the ‘too much choice’ effect. Both views are supported by sound evidence – it appears that the

argument has not yet been resolved. The question of whether the effect exists in consumer terms is still open and no solid conclusion can be made.

However, Scheibehenne’s (2009) paper proposes that the ‘too much choice’ effect may exist, only under certain conditions rather than being a universal effect as suggested by Iyengar and Lepper (2000).

In real life settings, it is clear to most that the effect does play a part in our satisfaction and decision making processes in consumption situations.

Further research outside a laboratory setting is proposed to examine the effects of the paradigm with ecological validity.

More investigation into the choice overload hypothesis is certainly called for as the arguments for and against its existence has not yet come close to reaching a concrete conclusion.
