I regularly speak to clients who ask questions like this: ‘I’m seeing this guy, who keeps sleeping with other women. Each time I catch him out, he promises that it’ll stop, but it never does. He drinks a lot and gets angry at me when he’s drunk. He hasn’t worked for years and I have to support him with my own money. But I believe that we’re destined to be together and that if I just love him enough, things will work out between us. When will he change?’ In moments like this, psychic ability is not required. Common sense is. Whenever clients present scenarios like this to me, I explain to them that the best indicator of a person’s future behaviour is their past behaviour, in the hope that this insight will act as a ‘wake up call’ to them. (Sometimes feelings of love, or infatuation, coupled with denial, can blind a person to the most obvious facts.)
This isn’t just my point of view though, there’s scientific evidence to support my opinion. You see, the field of psychology teaches us that one of the most reliable measurements of human behaviour is our ability to predict future actions based on past behaviour.
The Connection Between Past and Future Behaviour
The idea that past behaviour can be used to predict future actions is rooted in the concept of behavioural consistency. This principle suggests that individuals tend to behave consistently over time, particularly in situations that are similar or recurring. For example, if a person has a history of being punctual, it’s likely that they will continue to be punctual in the future. If a person has a habit of being spiteful and selfish, they probably will continue to act like this, too.
This consistency in behaviour can be attributed to several factors, including personality traits, habits, and learned responses. Personality traits, such as conscientiousness or impulsivity, can influence an individual’s behaviour across various situations. Habits, on the other hand, are repetitive behaviours that become automatic over time, making them difficult to change. Lastly, learned responses, such as conditioned reflexes, can also contribute to behavioural consistency.
The Role of Context in Predicting Future Behaviour
While past behaviour can be a useful predictor of future actions, it is essential to consider the context in which the behaviour occurs. Behavioural consistency may not always hold true in situations that are vastly different from those in the past. For example, a person who is punctual in their professional life may not exhibit the same punctuality in their personal life. And a person who’s aggressive to a spouse at home, might smile sweetly to the boss, at work.
To accurately predict future behaviour, it is crucial to understand the context in which the behaviour occurs. This includes factors such as the individual’s emotional state, the presence of external influences, and the specific demands of the situation. By taking these factors into account, we can better understand how past behaviour may or may not translate to future actions.
Applications of Predicting Future Behaviour
The ability to predict future behaviour based on past actions has numerous applications in various fields. In psychology, this understanding can help therapists and counsellors develop more effective treatment plans for their clients. By analysing a client’s past behaviour, therapists can identify patterns and predict how the client may respond to different therapeutic interventions. And by analysing the behaviours of those close to the client, a picture can emerge which might help the client to recognise the likely future actions of others in their lives (like in the example I gave above).
In the business world, understanding past behaviour can be invaluable in making hiring decisions and predicting employee performance. By analysing a candidate’s past behaviour, employers can gain insights into their work ethic, problem-solving skills, and potential for success in the role.
The power of past behaviour as a predictor of future actions is a fascinating and complex concept. While behavioural consistency can be a useful tool in predicting future actions, it is essential to consider the context in which the behaviour occurs. By understanding the factors that influence behavioural consistency, we can more accurately predict how individuals will behave in various situations. This knowledge can be applied in numerous fields, from psychology and counselling to business and marketing, to improve outcomes and achieve success.
