Overconfidence in personal decision making


The people who become decision makers in an organisation have experienced a lot of previous successful decisions and feats. There is a good reason for why they have become confident and being confident is a strong survival trait for a manager or a director. It is extremely difficult to point out when an individual or a group of people crosses the line and becomes overconfident, probably we can only tell it retrospectively.
And, the really interesting thing is that sometimes decisions that are rooted in overconfidence can lead to successes: the struggle to overcome the challenge might open up opportunities for new thinking, people or personal and organisational skills. Overconfident people have the gift to take an organisation to new highs, explore beyond its boundaries although can also lead to serious trouble (i.e.: the case study of Quaker in Certo, Connelly, Tihanyi, 2008).

Another interesting effect of overconfidence, especially when the decision maker seems highly and overly confident, is that this behaviour attracts many ambitious people – which again may turn an  initially overconfident decision into a successful one.

No wonder managers and entrepreneurs are overconfident – people with low confidence will not start a business or have a significantly lower chance to become managers or decision makers in an organisation (Certo, Connelly, Tihanyi, 2008).

I find the concept of metaknowledge very interesting and thought-provoking. We all use it to some extent and actively consider the depth and width of our knowledge and similarly our ignorance of a topic (Russo and Shoemaker, 1992) but being conscious about it is deliberating for me. I think there is an important link between metaknowledge and overconfidence: experienced managers understand metaknowledge, however acknowledging their limitations openly might be outside their comfort zone either for personal psychological reasons, for professional considerations or political agendas. They will act overconfident to avoid a situation they are concerned about.



In one of my previous workplaces as assistant general manager I had a difficult time dealing with a business unit manager, who was über-confident – a real loose cannon, who we finally had to restrain from making decision above a specific business value.

The base for his overconfidence was both the availability and the confirmation bias. His world view was in some way very simplistic and in the split second of finding available information supporting one of his ideas, he would make the decision. As an operations person, he had to make a huge amount of minor decisions and this bias actually made him a super effective person (he also had a lot of other highly valued qualities both professionally and as an individual). However, he applied the same mental processes to all the problems he encountered and I had to team up with other managers and thoroughly prepare for meetings involving him to make sure we are able to counter his availability bias with enough alternative scenarios to ponder.

His confirmation bias was an interesting case study for me in understanding how not to make decisions on complex business development issues. True, one needs to make bold moves in the development area, but in a highly saturated and competitive market it is difficult to come up with something new that will actually work. However, when this manager found one piece of supporting data or information for his pet idea, he would have started that business on the spot. This resulted in huge amounts of failed business attempts and inventories of products the company was hardly associated with rotting away in the corner of the warehouse.


The solution we came up to handle these issues was to always have two sessions on any business development idea, so everyone had time to research the case and to allow him to think about alternatives and contradictory information. Looking back, I think this was our effort to activate System 2 thinking and deploy metaknowledge.

Methodologies and tools for solving complex problems

As I started working on this entry I had to put on jeans and a hoodie for the first time since November when I first came to Broome. OK, I admit, it is still over 20O C, but has been too easy to get used to the normally searing hot days and nights. And, yes, winter is coming and it is high time to plan my winter holidays which will be summer holidays as I head home to Hungary, Europe, with my two friends, Melinda and Gergő.

The beauty of this exercise is that I have managed to make it mindbogglingly complex by trying to squeeze in as much fun as possible.

The first task was to go through cognitive mapping by collecting and combining data and then visualising information. In practice, it meant to ask the key stakeholders about their plans, choices and preferences. So we used chat and a conference call to find out all about it and realised we had needed to organise and visualise the data due to the complexity of the situation.

First of all, here are my priorities:
1.     spend at least a week with Melinda, my best friend
2.     spend a few days with Gergő, my other good friend
3.     meet my family in Budapest
4.     meet other friends
5.     make it to Lake Balaton with Melinda
6.     attend another friend’s, Adi’s wedding on 11th July close to Budapest
7.   can be done any time in June/August except 15-22 July and 8-15 August, as I work for a holiday resort and it is the peak season

Melinda’s priorities
1.  get a vacation AT ALL – she works for Unilever (UN:NYSE, www.unilever.com) in Katowice, Poland, as a project manager in the supply chain area and will have a major ‘go live’ on 6th July (UK) and immediately switching to the next region (DAHC)
2.     meet Gergő and myself
3.     meet her family in Budapest
4.     attend Adi’s wedding on 11th July
5.   make it to Lake Balaton on the week including the 19th Aug for the local festival called ZSKP (Gravy & Pickled Onion Sandwich Party, GPOSP)

Gergő’s priorities
1.     see his parents in August in the city of Miskolc when he is allowed to take a week off work
2.     attend Adi’s wedding on 11th July – he is flying in and out because he is on a really tight schedule: he works for Wrigley (William Wrigley Jr. Company, www.wrigley.com, part of Mars Inc) as an S&OP project lead in Munich, Germany, moving to Guangzhou, China in October
3.     meet Melinda and myself


We agreed to visualise this information in a simple, easy-to-use way, in Excel and share it through Microsoft OneDrive. This allows for modifications, comments and access from anywhere, anytime. And this is where we got with version 1.3:


Possible variations we discussed: project timing changes possible for both Melinda and Gergő at very short notice, ‘no vacation’ decision possible for Melinda.

Obviously, this is not a wicked problem: it is relatively simple. However, the unknown probability of the above factors that are outside the power of either decision makers mean that any decision will be highly risky.
We used group decision making as equals who respect each other and like each other enough to be honest - this enables us to enjoy all the advantages of the situation while minimises the negative effects of groupthink.

The solution we chose is one of subjective expected utility: although due to the simplicity of the problem we didn’t need to draw up an equation, we still needed to visualize the situation to come to a decision. We agreed that we could maximise utility (e.g. seeing each other) by László first joining Melinda in Katowice and then the two go to Hungary, while Gergő needs to change his August vacation period so all could meet. Also, this is a typical case of a decision made with bounded rationality: time and knowledge about certain important events is limited and all of us have distortions in perceiving the realities of the situation. We managed to satisfice: we all get what we wanted (the only exception is that I cannot make it to the wedding) and we will have the opportunity to kill just enough time together.

One interesting aspect of this actual situation was that I realised that while I normally use system 1 thinking processes way too much, adding people to the process slows me down to a healthy level and allows me for digging more deeply into the facts and see through my own biases.

It is a long post, so thank you for reading it all and here is a song about the little village called Balatonszepezd at Lake Balaton, where we plan to party:
