Why this? Why now?

At any moment, far more is happening around you — and within you — than you could possibly deal with. Some things pass straight through. Some become available without going any further. And occasionally something catches. ‘Wait a second … what’s this?’ NL calls that a snag. You may not know why it snagged. You may not even have deliberately decided to notice it. But something that might otherwise have passed has now become a candidate for more of your limited resources.

Before attention

Before you can deliberately think about something, judge it, investigate it or decide what to do about it, it first has to become available to you. That sounds obvious. But it puts an important question further upstream: What becomes available to this receiver in the first place? Looking is not necessarily noticing. Listening is not necessarily hearing what matters. A signal can be present without becoming available to you in a useful way. And what becomes available to you can change. The same signal can encounter the same receiver twice — and snag only the second time. Or the same signal can encounter two different receivers — and snag one but not the other. The signal may be the same. The receiver isn’t.

Can you perceive the difference?

Something can be different without you noticing the difference. The question is not only whether a difference exists. It is whether this receiver has sufficient resolution to perceive it. A novice and an expert can encounter the same situation and notice different things. Experience can build a richer model of normal. And a richer model can make finer differences available: • That sound is slightly different. • Something is missing. • That movement doesn’t quite fit. • They don’t normally say it like that. What once passed unnoticed may now snag. That is one way learning can change what becomes available to notice next.

But expertise isn’t enough

There is a tension here. A richer model of normal can help you notice increasingly subtle differences. But the more familiar and successful that model becomes, the easier it may be to stop questioning the model itself. You become very good at seeing differences within your existing way of looking. But what if the way you are looking is part of the problem? So: Build the model. But remain open to questioning the model. Sometimes another receiver helps. A novice asks a question the expert stopped asking years ago. Someone from another field sees a connection the specialist didn’t. Another point of view makes something familiar look strange again. Difference can help you use your model. And sometimes difference gives you a reason to question it.

Respect the snag

It snagged for a reason. Respect the snag. But respect does not mean obey. A snag does not tell you: • this is important; • this is true; • this is dangerous; • this is good; • you should act. It tells you something much smaller: Something about this was sufficient to snag this receiver, here and now. You may not yet know why. So ask: • What’s this? • Why did this snag me? • Does it deserve more of my limited resources? A snag is not a verdict. It is a potential claim on finite resources.

Why did this snag me?

Sometimes the reason tells you something about the signal. Sometimes it tells you something about you. Something may snag because it frightens you. Excites you. Flatters you. Angers you. Confirms something you already believe. Offers something you badly want. And sometimes another receiver may know that. There is a Russian saying: ‘The only free cheese is in a mousetrap.’ The mouse has not failed to notice. It has noticed exactly what someone wanted it to notice. The cheese may be real. The benefit may be real. But neither has to be the whole representation. So sometimes there is another useful question: Why might someone want this to snag me? The aim is not to become suspicious of everything. If something looks too good to be true, it might be. It might simply be worth another look.

Not every snag deserves more

Respecting a snag does not mean investigating everything that catches you. You couldn’t. Your attention is finite. Your time is finite. Your effort is finite. Some snags deserve a fraction of a second. Some deserve another look. Some may deserve full cognitive power for a short time. And some deserve nothing more. The question is: What, if anything, does this snag deserve? That question takes us from noticing towards resource allocation and judgment.

Could we get better at noticing?

Not by noticing everything. That would be impossible — and probably unbearable. But perhaps we can become capable of noticing one useful difference that would previously have passed us by. • Experience may help. • Training may help. • Another receiver may help. • Changing perspective may help. • Building a richer model of normal may help. • And remaining willing to question that model may help too. Perhaps we can also become better at recognising when something that snagged doesn’t deserve any more of us. One difference noticed that would previously have passed. One snag given another look. One snag deliberately allowed to pass. That’s enough.

Go deeper

Models of normal What makes something feel normal — until it doesn't? What you notice depends partly on what you already expect. Explore models of normal, familiarity, difference and how the receiver changes what can snag.  Finite resources You can't give everything everything. Attention, time, effort and other resources are limited. Explore how finite beings decide what deserves more, what deserves less — and what to keep in reserve.   Judgment What makes one option seem better than another? Judgment is comparative. Explore choices, thresholds, confidence, elimination, commitment — and the question: What unit? What ruler? What period of time?  Learning What changes the receiver? Learning doesn't just add information. It can change what becomes available to notice next. Explore snag-led learning, banking, resolution, changed receivers and how one block can make the next block possible.  Difference Different from what? Different enough to matter? Difference depends on the receiver, the comparison and the resolution at which we look. Explore difference, similarity, resolution, thresholds — and why changing the ruler can change what becomes visible. 
