Ethics Explainer: Logical Fallacies

A logical fallacy occurs when an argument contains flawed reasoning. These arguments cannot be relied on to make truth claims. There are two general kinds of logical fallacies: formal and informal.

First off, let’s define some terms.

  • Argument: a group of statements made up of one or more premises and one conclusion.
  • Premise: a statement that provides reason or support for the conclusion
  • Truth: a property of statements, i.e. that they are the case
  • Validity: a property of arguments, i.e. that they are logically structured
  • Soundness: a property of statements and arguments, i.e. that they are valid and true
  • Conclusion: the final statement in an argument that indicates the idea the arguer is trying to prove

Formal logical fallacies

These are arguments with true premises, but a flaw in its logical structure. Here’s an example:

  • Premise 1: In summer, the weather is hot.
  • Premise 2: The weather is hot.
  • Conclusion: Therefore, it is summer.

Even though statement 1 and 2 are true, the argument goes in circles. By using an effect to determine a cause, the argument becomes invalid. Therefore, statement 3 (the conclusion) can’t be trusted.

Informal logical fallacies 

These are arguments with false premises. They are based on claims that are not even true. Even if the logical structure is valid, it becomes unsound. For example:

  • Premise 1: All men have hairy beards.
  • Premise 2: Tim is a man.
  • Conclusion: Therefore, Tim has a hairy beard.

Statement 1 is false – there are plenty of men without hairy beards. Statement 2 is true. Though the logical structure is valid (it doesn’t go in circles), the argument is still unsound. The conclusion is false.

A famous example of an argument that is both valid, true, and sound is as follows.

  • Premise 1: All men are mortal.
  • Premise 2: Socrates is a man.
  • Conclusion: Socrates is mortal.

It’s important to look out for logical fallacies in the arguments people make. Bad arguments can lead to true conclusions, but there is no reason for us to trust the argument that got us to the conclusion. We might have missed something or it might not always be the case.


How to deal with an ethical crisis

The recent dissection of CommInsure’s heartless treatment of some of its policy holders (including fellow employees) by Fairfax Media and ABC’s 4 Corners program reinforced every bad stereotype there is about the world of banking and finance.

The people whose stories were featured in the reports were treated in a manner that made me wince. You’d think that people of even moderate decency would have realised that what was being done was wrong. Yet the evidence is incontrovertible.

Basic decency was set aside in favour of the financial interests of the corporation and, one suspects, the people making the decisions. Until now, the cost of this has been borne by those whose claims were denied.

Now the price is being paid by the Commonwealth Bank and the vast majority of innocent employees who will have been appalled and ashamed by what has been revealed.

Now that the issues have been exposed, the first order of business should be to remedy the harms that were caused to individuals who had a right to expect that their legitimate interests would not be sacrificed for commercial gain.

The particular vulnerabilities of those affected make for especially chilling stories. No person, whatever their circumstances, should have the careful parsing of the language of insurance policies turned against them. We all buy insurance in the expectation that it will be available when we really need it. It is just plain ‘tricky’ when loopholes are used to deny our reasonable expectations.

It is time that we developed a more mature understanding of what it means to live an ethical life as an individual or as an organisation.

The second order of business must be to rescue the concept of ‘ethics’ in banking and finance. In recent months, I have spoken to a number of senior leaders in the banking and finance industry about their signing the Banking + Finance Oath. As things stand, about 600 people have made a personal commitment to the tenets of the Oath. Every person with whom I have spoken supports what the Oath says and stands for.

However, quite a few are reluctant to sign for fear that something might go wrong – and that in the face of evidence of ‘ethical failure’ they will be accused of hypocrisy.

Their misgivings are understandable – especially after the CommInsure scandal. It was only at the CBA’s last AGM that the Chairman and CEO both raised the issue of ethics – making a commitment to become an “ethical bank“. At the time, cynics scoffed at the idea. In recent days, and quite predictably, the CBA has been ‘hit over the head’ (clobbered is probably the better word) with this aspiration. No wonder people are nervous about making a public commitment to ethics!

The Ethics Centre worked extensively with the CBA in late 2014 and early 2015 (but not with CommInsure) and I have a high regard for the sincerity with which they laid out a path for ethical development at the 2015 AGM. What was said then should not be dismissed out of hand – and especially not because of recent events. Rather, we should ensure that the standard by which we assess the CBA is a reasonable one – and then judge accordingly.

To think that any individual (other than a saint) can achieve ethical perfection is unfair and unrealistic. I certainly wouldn’t measure up to that standard.  To think that an organisation of 50,000 people will be perfect is just ridiculous. What we can (and should) expect is that an ethical organisation will distinguish itself with a number of key features.

First, it will actively seek to reinforce the application of its values and principles – not just at the rhetorical level but as part of an ongoing program to root out and eliminate all systems, policies and structures that might subtly (and not so subtly) lead people to act in a manner that is unethical.

Second, it will build a culture of open communications in which people are rewarded (and certainly not punished) for drawing attention to practices that appear to be inconsistent with the organisation’s declared ethical framework.

Third, an ethical organisation will be marked by the quality and character of its response to ethical failure. For example, it will own up to its own failings. It will remediate and compensate for any harms done. It will ensure that the lessons to be learned are widely published for the benefit of others. It will aim to do what is right – and not just the minimum that it is required to do.

This third aspect was evident in Ian Narev’s response to questioning on Four Corners. I believe his expressions of concern were sincere and that he will follow up, personally, with the affected individuals. Beyond this, I have no doubt (but no certain knowledge) that he is leading a process that will meet the expectations outlined above. That CBA follows this path will be a surer indication of its commitment to ethics than the fact that this shameful series of events occured in the first place. And that is what we need to evaluate.

An ethical organisation will be marked by the quality and character of its response to ethical failure.

It is time that we, in society, developed a more mature understanding of what it means to live an ethical life as an individual or as an organisation. If we cannot be perfect, then we can at least be held to account for the sincerity with which we make our best efforts to act, in good conscience, in conformance with our chosen values and principles.

And second, we should be accountable for the competence we bring to bear in our ethical decision-making – it’s a skill that cannot be taken for granted and needs development through active, reflective practice.

If this (rather than perfection) was the standard we insisted on – for ourselves and others – then more people in the world of banking and finance might publicly commit to what they know, in their heart-of-hearts, to be right and good.
