Is “I didn’t think it was serious” a good excuse? When does it stop being one?
After something goes badly wrong, people who did nothing often say: “I didn’t think it was serious.” Sometimes that is true and fair. Sometimes it is an excuse for not wanting to know. Working out the difference is important, both for judging others fairly and for thinking about how we should behave ourselves.
In the case behind these seminars, about fifty members of a fraternity group chat reportedly received messages and a photo during the night of the alleged assault, and no one called the police. We do not know what any individual saw or what they thought it meant. But it is likely that some of them, if asked, would say they did not think it was serious. Should we accept that?
When it is a good excuse
Not realising something was serious can be a genuine excuse. We do not blame people for failing to respond to dangers they could not reasonably have recognised.
Imagine you see a message that is genuinely ambiguous: a blurry photo with no context, or a vague comment that could mean many things. You might reasonably assume it was a joke, or that someone was exaggerating. If it later turns out that something terrible was happening, it would be unfair to blame you as if you had known.
Similarly, if you saw the message hours later, after the event, you could not have prevented anything by acting immediately.
In these cases, the excuse works because you did not know, and it was reasonable not to know.
When it stops being a good excuse
The excuse becomes weaker, and eventually fails, in several situations.
When the signs were clear. If a message described someone as unconscious, or showed someone obviously unable to look after herself, then “I didn’t think it was serious” is hard to believe. A reasonable person would have recognised the danger.
When you chose not to look closer. Some people avoid finding out the truth because they suspect it will be uncomfortable. They do not read the message properly, or they put the phone away quickly. Philosophers call this wilful blindness. If you deliberately avoided knowing, you cannot use your ignorance as an excuse. English criminal law takes a similar view in some contexts: deliberately shutting your eyes to the obvious can count as knowing.
When the group’s attitude shaped your judgement. If you thought it was not serious mainly because others were joking about it, you need to ask whether your judgement was really your own. Following the crowd’s mood is understandable, but it is not the same as reasonably concluding that everything was fine.
When it would have been easy to check. If you were unsure, you could have asked: “Is she OK?” or “What’s going on?” If checking would have taken seconds and you did not bother, your uncertainty is partly your own choice.
When the stakes were very high. The more serious the possible harm, the more reason there is to take even an uncertain risk seriously. If there was even a reasonable chance that someone was being seriously hurt, that chance alone was enough to justify acting.
Why the excuse is so common
Part of the reason people reach for this excuse is that it protects how they see themselves. Most of us want to believe we would help someone in danger. Admitting that we saw the signs and did nothing is painful. Saying “I didn’t think it was serious” lets us keep believing we are good people who simply misread the situation. That is a very human reaction, but it can get in the way of learning from what happened.
A useful test
One way to test whether the excuse is genuine is to ask: what would a sensible, caring person have thought in your position, with the information you had? If they would also have thought it was not serious, the excuse is fair. If they would have been worried, the excuse fails.
Another test is to ask whether you would accept the excuse from someone else. If a friend of yours was the person in the photo, and someone in the chat said “I didn’t think it was serious”, would you accept it?
Questions for discussion
Have you ever not acted because you did not think something was serious, and later realised it was? What made you misjudge it? How can we get better at recognising when something is serious? And is it fair to judge people more harshly for not realising something if they could have found out easily?
