Anxiety and some kinds of neurodivergence can make the uncertainty inherent in an event a real barrier to participation. These sorts of issues can be easily overlooked and can result in excluding people who could have participated with the right support. Accessibility isn’t just about whether a person can physically get into the space, barriers are not just about bodies.
I’m no great expert on neurodivergence. My understanding is that unfamiliar things, changes to routines, and other kinds of uncertainty can be immensely stressful for some neurodivergent people. Knowing things in advance so as to be able to feel prepared can make a great deal of odds and reduces anxiety.
I do know a fair bit about anxiety. Given an empty space, the anxious brain will just go ahead and plug in disasters. The more you know, the less room there is to unleash the panic weasels, and the more manageable the situation becomes.
What kind of thing a person needs to know about is probably going to be quite variable. Based on what I’ve seen around event organising, the most important thing is not to be complacent around requests for information. Don’t assume people are being unreasonable or demanding if they need to know about something ahead of time. Also, they probably aren’t going to tell you if they have sensitivity issues caused by autism, or a hard time imagining unfamiliar things, or are checking to avoid trauma triggers, or need to stop their brain from coming up with a hundred potential disasters.
If you don’t know exactly how something is going to work, tell people what you do know – try and work out what the limits are. Consider asking if there’s any kind of information they need. Make it ok for people to step out if something turns out to be too much for them. Actively support people whose psychological needs are different from your own and don’t expect everyone to be the same.
It shouldn’t matter why people are asking for information and help – in that we should not have to be persuaded they have a specific need in order to act on requests like these.
