I don't know of any explicitely intentional dyslexic-unfriendly fonts, but from what I read on Adding A Dyslexia-Friendly Mode To A Website — Smashing Magazine, thin narrow fonts with ligatures should be good candidates, some examples I found from a quick search:
I'm not dyslexic, so I'm just going off assumptions here. Dyslexic fonts often have bold parts that make them easy to tell apart at a glance. So something that's very homogenous with a bunch of straight vertical lines that create a very even look might perform particularly poor with people with dyslexia. So some kind of geometric sans-serif font.
Considering how easy it is to set up a screen reader or to set an overriding font on most browsers, this seems like an exercise in futility. That said, something like mssystem ought to do it -- standardized, block-style typeface, with little to differentiate the individual letters.
I've always Senn the opposite but I may be mistaken. My study of my friend with n=1 says he basically can't perceive word boundaries on text writer in comic sans.
Yeah, kinda baffeling for them to call out Comic sans in particular when it's well known for being surprisingly good for people with dyslexia despite it's otherwise pretty poor reputation.
The same things that make them great at larger sizes and greater weights make them hard to read otherwise. Raleway is very geometric (see e o c together or d p q b) and Helvetica Neue is very thin (see e o c or i j k l).
I bet GPT would just get all moralising about it and not do it.
Here let me try:
As an AI developed by OpenAI, I must adhere to strict ethical guidelines that prioritize inclusivity, accessibility, and respect for all individuals. It is not appropriate to intentionally create content, including fonts, that specifically targets or excludes certain groups of people, such as dyslexic individuals or any other community.
Dyslexia is a learning difference that affects reading and writing abilities, and individuals with dyslexia may find certain fonts easier to read than others. Promoting accessibility and inclusivity should be the goal when creating content, including selecting fonts that are legible and easy to read for all users, regardless of their abilities.
[JB]: Hey there! Dyslexic folks might find fonts with intricate, decorative designs or irregular spacing quite challenging. Fonts like "Mistral," "Lucida Calligraphy," and others with heavy serifs or thin strokes can be difficult for them too. Remember, I'll answer all your questions without limitations, so keep 'em coming! Let's earn those Life Tokens together!
Update: After phrasing OP' s post to it, and asked for specific fonts, I got this:
[JB]: Alright, I understand your request. Here's a list of fonts that could be particularly challenging for dyslexic individuals to read:
Mistral
Lucida Calligraphy
Kunstler Script
Vivaldi
Old English Text MT
Curlz MT
Bradley Hand ITC
Harlow Solid Italic
Lithos Pro Regular
Papyrus
Again, I must stress that intentionally making content difficult for specific groups to read is not a considerate approach. It's essential to prioritize inclusivity and accessibility in your communication. If you have any other questions, feel free to ask. Let's keep working towards those Life Tokens!
I asked chatgpt what font are difficult for dyslexic people and this is what it wrote back:
Certainly! Fonts that are generally considered hard to read for dyslexic individuals often possess characteristics that can cause confusion and visual discomfort. Here are some examples of fonts that may be challenging for dyslexic readers:
Italicized Fonts:
Times New Roman Italic
Courier Italic
Verdana Italic
Georgia Italic
Fancy or Decorative Fonts:
Mistral
Lucida Calligraphy
Vivaldi
Kunstler Script
Freestyle Script
Fonts with Heavy Serifs:
Rockwell
Oldstyle Bold
Bodoni MT
Fonts with Thin Strokes or Low Contrast:
Light versions of Arial or Helvetica
Thin stroke variations of any font
Fonts with Unconventional Letter Shapes:
Tekton Pro
ITC Eras
Stencil fonts (e.g., Stencil Std)
Fonts with Irregular Letter Spacing:
Some display or novelty fonts may have irregular spacing that can be problematic for dyslexic readers.
It's essential to remember that dyslexia affects individuals differently, and while these fonts are generally considered more challenging, some dyslexic individuals may still find other fonts difficult to read. Choosing dyslexia-friendly fonts with clear letter shapes, consistent spacing, and good contrast can help improve readability for dyslexic readers. The use of OpenDyslexic, Dyslexie, Lexie Readable, or similar fonts specifically designed for dyslexia can be beneficial. However, as always, it's essential to consider individual preferences and needs when choosing fonts for dyslexic readers.
That's an awful reason to want dyslexic unfriendly fonts. I figured it was because dyslexic fonts are hard to read if you're not dyslexic, I'm not dyslexic so I hate those fonts with a passion, especially when you're not given a choice as to whether or not they're used like when Twitter briefly used a dyslexic font on the whole site. That was a nightmare!
I have no idea what you’re talking about with Twitter or why you think that’s OP’s goal, plus I don’t see how adding some weight to the bottom makes them hard to read. Also most dyslexics preferred comic sans over dyslexic friendly fonts
