k. Causality and Behavioural Strategies

Causality and Behavioural Strategies

We interact with the physical world and influence events using the rules of causality. Most of us do this unconsciously, but there is advantage in understanding the process. This better enables us to verify our decisions.

Causality can be complex, with several causes combining to produce an effect. These causes can be of two types: necessary causes, in the absence of which the effect cannot occur; and sufficient causes, in the presence of which the effect must occur. The epidemiologist, Ken Rothman, explained that, for an effect to take place, it is often the case that several necessary causes must combine to create a sufficient cause. For example, the presence of gas, oxygen and a spark are each necessary and together sufficient to cause a gas explosion.

Causality also involves inhibitors, i.e., those things which always prevent an effect from taking place, even if sufficient cause is present. These inhibitors can also be of two types: sufficient inhibitors, in the presence of which the effect cannot occur; and necessary inhibitors, or those things required to prevent an effect. Again, a sufficient inhibitor may comprise one or more necessary inhibitors.

We can use this knowledge in our strategies to achieve a desired outcome. This is best demonstrated by a simple example. Suppose we know that an effect, e, occurs as a result of two necessary causes, a and b. Together, a and b are a sufficient cause.  In the absence of a, b, or both, e cannot take place. So, if we wish to prevent e, then our strategy may be to prevent one of a or b, whichever is easiest. However, the effect can also be prevented by two sufficient inhibitors, c or d. In the presence of c, d or both, e cannot occur. Thus, an alternative strategy for preventing e, is to cause one of the inhibitors c or d, whichever is the easiest.

In this example, the presence of a and b and the absence of c and d result in e. If some but not all of these conditions exist, and e is undesirable, then this is a risk. However, if e is desirable, then it is an opportunity.

Our behaviour often steers events by increasing or decreasing their likelihood, rather than directly causing or preventing them. For example, we may lack the resources to directly cause an event, and may only have sufficient to enable it. To benefit from such behaviour, we must observe our environment, identify the opportunities and risks that it presents, and intervene to our advantage.

Typical strategies are as follows.

Enablement means acting to remove any existing inhibitors. Note that sufficient cause may not be present. So, the effect may not actually occur, but only become able to occur.

Facilitation means acting to introduce necessary causes where previously they were absent. Note that not all necessary causes may be present and not all inhibitors absent. So the effect may not actually occur, but merely become more likely.

Risk Reduction means acting to reduce the likelihood of an effect. It will not yet have occurred, either because an inhibitor is present, or because not all necessary causes are present. We can reduce the risk yet further by removing more necessary causes.

Prevention means acting to introduce an inhibitor where none is present. Note that the effect will not yet have occurred because not all necessary causes were present.

i. The Behavioural Loop or Cycle

The Behavioural Loop or Cycle

Our behaviour is always ongoing. When one need is satisfied or contra-need avoided, we move on to another. In every case, we make our decisions in a similar way, and there is, therefore, a behavioural loop or cycle as follows.

  1. Our most pressing needs or contra-needs are identified through their impact on our emotions. That is, we identify the greatest cause of dis-satisfaction.
  2. Potential options for acquiring satisfiers and avoiding contra-satisfiers are identified, drawing on individual or group knowledge and experience.
  3. The resources needed to acquire those satisfiers or avoid those contra-satisfiers are assessed, again drawing on individual or group knowledge and experience.
  4. The resources that we control are assessed. These resources may be our own or those of others.
  5. Possible courses of action are assessed for their potential impact on our emotional state, taking into account the following:
    • All affected personal needs and contra-needs.
    • All affected needs and contra-needs of significant others.
    • Whether we will receive positive or negative regard, and what is needed to enhance the former or mitigate the latter.
    • Whether we will feel psychological satisfaction or guilt, and what is needed to enhance the former or mitigate the latter.
    • If the likelihood of achieving the desired result is uncertain, we also assess the impact of not achieving it. Whether we proceed with a course of action will depend on the benefit we hope to achieve, the likelihood and consequences of failure, and our personality.  Most people, for example, will not use all their available resources in a single high risk, high return activity.
  6. Generally, when seeking a satisfier, we have two potential routes. We may wait until an opportunity arises by chance or attempt to create one. Similarly, when seeking to avoid a contra-satisfier we have the options of waiting until it arises or seeking to pre-empt it. Which route we choose depends on the net emotional benefit gained. This in turn depends heavily on the resources required to create an opportunity or pre-empt a contra-satisfier.
  7. Those actions that are within the resources available to us and which have an emotional benefit are implemented. We do not normally seek to optimise our choices, because this, in itself, requires substantial resources. Rather, we choose an option which is both satisfactory and sufficient and reject options which have an overall disbenefit. This is known as “satisficing”, a term coined by the American political scientist, Herbert A. Simon, in 1956.
  8. The outcome of the action is observed and remembered for the future. If it has been successful, then this will reinforce the behaviour, i.e., we are more likely to repeat it in similar circumstances. If it has failed, then the behaviour involved is less likely to be repeated. Repetitive failure will cause it to become extinguished.
  9. The entire process is then repeated indefinitely. However, as time progresses our needs and contra-needs alter, and different ones come to the fore. For example, the physiological needs for food and sleep increase in priority if not satisfied. We can also learn from experience and become more adept at choosing efficient and successful forms of behaviour.

Research has shown that emotions can carry over from one decision to the next without us being aware of it. These incidental emotions can be difficult to detach and can influence subsequent decisions. For example, people who previously experienced anger are more prone to blame others in subsequent decisions, and people who previously experienced sadness are more prone to blame general circumstances. Fearful people make more pessimistic judgements about the future, and angry people are more optimistic. It is thought that the best way to avoid this emotional carry over is to develop greater emotional awareness.

c. How Needs and Contra-Needs Motivate Us

How Needs & Contra-Needs Motivate Us.

Variational Principles

Variational principles exist widely in the physical world. They state that a physical object, system, or event will behave in a way which minimises or, in some cases, maximises some physical quantity. The most famous of these is Fermat’s Least Time Principle which states that the path taken between two points by a ray of light is the path which takes least time.

Similar principles apply to human decision-making and behaviour. We will first attempt to satisfy the need which has greatest value to us, i.e., the need which is most pressing. Furthermore, we will attempt to satisfy it in a way which demands least use of personal resources or the resources of those close to us.

First Variational Principle – Pressing Needs

Behaviour is physical action or communication to satisfy our needs. It involves the application of resources available to us. Behaviour can be simple, i.e., directed towards a single need, or complex and directed towards several needs. In Maslow’s view, most behaviour is multi-motivated, i.e., determined by several needs rather than just one. For example, eating may satisfy one’s hunger, need for comfort, and need to socialise.

We tend to address our most pressing needs first, but priorities differ according to the individual and circumstances. The behaviours that we adopt contribute significantly to the perception of our personality, therefore.

Second Variational Principle – The Efficient Use of Resources

People aim to satisfy each personal need as efficiently as possible, i.e., in a way which yields the maximum benefit for the least expenditure of personal resources. For example, if a person walks across a park to a gate in the opposite corner he or she will do so in a straight line unless other needs are satisfied by not doing so. In this way our resources can be used to provide greatest satisfaction across all our needs.

The Role of Emotion in Decision-making

Many higher animals experience emotion and, in the human being, evolution has built on that foundation. Most psychologists now recognise that emotions are an integral part of the human reasoning and decision-making process. They are not, as so often portrayed, the enemy of reason. We may be able to make a logically or mathematically based decision in very simple circumstances, such as whether to buy 4 apples for a pound at one stall or five identical apples for a pound at another. However, the circumstances surrounding most decisions are far too complex for this. In such circumstances, it is emotions that motivate our behaviour. They are used to “tot up” the effects of satisfiers and contra-satisfiers, i.e., those things which cause our needs to be satisfied or which cause harms we wish to avoid.

We experience several basic emotions, and they fall into two classes. Those associated with satisfiers are regarded as positive and those associated with contra-satisfiers are regarded as negative. Our decisions aim to improve our overall emotional state by increasing the former and reducing the latter. Note that it is satisfiers and contra-satisfiers, i.e., external causes, that are evaluated rather than our internal needs and contra-needs. So, for example, the presence of a contra-satisfier such as a disease, and the absence of a satisfier such as food will both contribute to a negative emotional state.

Our overall emotional state depends on whether the status of each satisfier or contra-satisfier is: absent; latent; precarious; or entrenched. Here, “latent” means capable of manifesting, for example when a satisfier is promised, or a contra-satisfier threatened. “Precarious” means present but insecure. “Entrenched” means present, solidly established, and unchangeable.

Emotions are experienced on a scale from mild or non-existent to strong or overwhelming, depending on the priority of the need or contra-need and the status of the satisfier or contra-satisfier. Most of the time our emotions are low key, for example a mild feeling of discontent, and we are capable of consciously verifying our decisions and making rational choices. These lower key emotions are used to “tot up” the predicted effects of our decisions before they are implemented. For example, if we decide to behave in an anti-social manner, then we are likely to predict social censure, which is of course a contra-satisfier. This will contribute to feelings of anxiety which may cause us to alter our decision.

However, when emotions are very strong or overwhelming, we experience stress. Hormones are released which prepare our bodies for swift action in the face of an immediate risk or opportunity and we respond almost entirely unconsciously. This is, of course, an inherited survival mechanism which, on average, enables us to survive and prosper when there is no time for the conscious verification of our decisions. It does, however, carry with it a strong risk of error.

When making more considered decisions about our behaviour we carry out a form of risk/benefit/cost assessment. In this context, “risk” means the likelihood that our behaviour will result in the anticipated benefits and/or dis-benefits. “Cost” is the value that we place on the resources used.

The “benefits” of any behaviour are reductions in negative emotions, such as fear and grief, and increases in positive emotions, such as happiness. These benefits are due to increases in the status of satisfiers and decreases in the status of contra-satisfiers. For example, a benefit results when access to food increases or when a risk of disease decreases.

Dis-benefits, on the other hand, are increases in negative emotions and decreases in positive emotions. They are due to decreases in the status of a satisfier or increases in the status of a contra-satisfier.

Benefits and dis-benefits can of course, cancel one another out and, depending on their relative magnitude, may yield a nett benefit, no overall benefit/dis-benefit, or a nett dis-benefit. The magnitude of benefits and dis-benefits are, in turn, determined by several factors related to needs and contra-needs which will be described in a future article.
