"authoritarian governance is defined by highly concentrated power structures that repress dissent and emphasize submission to authority, social conformity, and hostility towards outgroups"
... is a very problematic way of articulating this - to the point of promoting ignorance, because it's frankly how someone with a Liberal Democratic mindset would describe the system, but not others. I would argue that it's not objective because it may not capture the essence of such systems, rather, it just highlights the 'downsides' as seen from the other side.
Others might describe systems as possibly more collective or communitarian wherein legitimate central authorities have considerably better ability to manage affairs, particularly wherein such controls can have a material effect, i.e. 'pandemic', 'war' and maybe even things like infrastructure or other national challenges.
What people in 'liberal democracy' might see as 'individual choice', others might see as 'selfish, self-interested' possibly 'greedy' behaviour, actions that show little regard for others, only the self. The natural result of such behaviours might be 'inability to respond in a coherent manner to collective problems'.
Of course, where there is centralised power, there's an opportunity for it to be corrupt wherein you might have arbitrary and bad acting here and there, but I don't think to describe a system by its downsides is right.
This is especially important because the correlation may not be with authoritarianism as described, but possibly with group unity, collectivism or something else.
Edit: I should add, systems with strong 'central control' that some might describe as 'authoritarian' like Singapore, South Korea etc., have tamed and controlled Coronavirus and have exemplary responses. Their economies are not collapsing, they are in school, they are not dying en masse.
Meanwhile, 'Liberal Democracies' economies are collapsing, facing massive casualties, dying in hordes.
Imagine how stupid we must look to them? They literally showed us 'how to do it' but we're either too self-focused or possibly 'don't understand' how they are organized.
