Critiques are two-way. It is not just one person providing critical feedback, but rather the designer articulating the rationale for their decisions (why they made the choices that they did) and the critic responding to those judgements. The critic might also provide their own counter-judgements to understand the designer’s rationale further.The critic in a critique must engage deeply in the substance of the problem a designer is solving, meaning the more expertise they have on a problem, the better. After all, the goal of a critique is to help someone else understand what you were trying to do and why, so they can provide their own perspective on what they would have done and why. This means that critique is “garbage in, garbage out”: if the person offering critique does not have expertise, their critiques may not be very meaningful.
I totally agree that critiques should be a two-way conversation rather than just one person pointing out flaws. It makes a lot more sense when both the designer and the critic are actively explaining their reasoning because it feels more collaborative that way. I also like the idea that critiques are only as good as the person giving them as it reminds me how important it is to get feedback from people who actually understand the problem you’re solving.
