Recency Bias – by the name itself, we can able to understand that, we forecast/predict the future scenarios based on the recent performance/situations etc. It is the human tendency to focus more on the recent events rather than long time. Some of the examples mentioned below
Performance appraisal is considered the most impacted by the recency bias. In general, before appraisal, if we have done some good job which is considered as good performance. Even if, that there is a poor performance during the entire year.
I am thinking to go on a road trip. some of my friend mentioned that the highway/road no.123 is very dangerous due to accident happened 6months back. But this road use to consider as one of safest road due to zero accidents in last 5 years. So due to recency Bias, I tend to choose that road is unsafe.
I am going to buy brand A phone. But my friends told me that the phone is very good, due to its recent performance & battery backup is good. Based on this feedback I brought the phone, but it is not working well. As the past performance of this type of phone is very bad. I could have saved money if I brought Brand B phone, which has good performance in the past.
In a manufacturing line, one of the parts is failing from last 6 months. But in the past, there is no records of failure. Due to recency bias, I tend to decide that this equipment is a chronic problem for this manufacturing line.
In service sector, I am going on vacation to other countries, I would like to stay in hotel XYZ, but the experience in last month visit was very bad, because during the visit, there was some construction work going on. But in the past the experience is always good. If I stay in Hotel ABC, my expenses will be 2times. With out recency bias, If I would have stayed in the hotel XYZ, I could have saved money.
In the chemical making line, one of the equipment failed recently, then the root cause was base vibration bolts are loose. If the equipment failed, operators are tending to tightened the bolts, instead of investigating the problem in details
If we don’t consider the recent bias in project decision making, it may give short term benefits rather than a long-term benefits. For example, in the improve phase we identified that the one of the equipment speeds should increase to get the better quality. But recently the equipment got failed to high vibration due to some other reason. But while implementation, team will not approve this decision of increasing the speed of equipment. In this situation, if we could have the data like equipment history and root cause of last failure, we might have increased the speed without hesitation. Which will also improve the quality.
The reason for recency bias
Memory and Attention – We tend to recollect more recent information & prioritize the recent over the old
Availability Heuristic – People often rely on the recent available information, rather than the old
Impacts of emotion – Recent events evokes stronger emotions, which impact decision making
Short-term memory bias – Events or information that occurred recently are most likely to be at priority for the individuals, which influence the decision making or the judgement
Cognitive load – The busy work environments and lot of information (cognitive load) challenging to consider the person’s performance over a period of time. This will impact the decision making
Recency’s perceived relevance – We always assume that the recent events are the more indicative of the performance (most recent information is most relevant) which also impact the decision making.
Some of the ways to avoid the recency bias:
Data – Get enough data before making decision. In the above example of equipment failure, we need to see the equipment history, PM schedules, vibration analysis report, OEM recommendation of failure, process conditions, then only we can take decision of overhauling of equipment, change with new equipment
Look at the Big Picture: Instead of focusing on what’s happening now, try to consider what has happened in the past. If we’re thinking about building new manufacturing plant, we need to look at how the returns gave over years of similar business.
Standardized procedures: These procedures are can reduce the subjectivity & feelings of recent bias. In the same example, we can say that before buying a new equipment. Engineers need to bring all the relevant information, and do the proper analysis of the data and estimate the life of equipment. Even some time, we can refer to benchmark life of the equipment within the business.
Training: Raising the awareness within the team to avoid the recent factor. Which helps focus on the historical events/data/situations rather than the recent ones.
Get Different Views: By talking to people who might see things differently or consider other time frames. The SMEs/consultants comes up with more experience of various industries & expertise. They can validate properly about the recency bias of events/situation and also may guide for right decision.
Slow Down: Try to avoid making quick decisions based on the recent events. By taking more time can help us to think things through more thoroughly
Use a performance review system : Try to use the online system to track the performance. So that the data can be summarized for decision making
