This seems to something that can be objectively measured.
What is the cutoff for when something is a spike? Would a fifty percent increase count? Would tripling count?
Does this change based on earlier figures? For example, someone could say that an increase of fifty percent from 0.02% to 0.03% is not a spike, but an increase of fifty percent from 1% to 1.5% is a spike.
The answer to these questions should be the same regardless of how you feel about it (Is it good? Is it bad? Is it concerning? Is the main response indifference?)
I can certainly agree that too many conservatives believe misinformation, but a measure of viral stories on social media isn't necessarily going to demonstrate that conservatives are worse than Democrats.
An easy explanation is that stories that favor Democrats are likely to appear in multiple places, so the odds that any one story will go viral are reduced. Julie Swetnick says that she witnessed Brett Kavanaugh participate in habitual gang rapes in Suburban Maryland when he was a teenager, and that's covered in a lot of places.
A few years ago a science blogger went viral based on an interesting concept (the most recent winter solstice is the longest night in Earth history because tidal friction is causing the Earth's rotation to slow down at a rate of a millisecond a century) that had obvious flaw he was unaware of (there is variability from other causes that means some days are milliseconds longer than others as measured.)

A big reason the story went viral is that it was unique. No one else was reporting it. The reason for that is that others did their due diligence and would realize the error.
If CNN, the New York Times, the Washington Post, Vox and BBC are all reporting something big, their website's version is unlikely to go viral because it is covered by everyone else.
If we really wanted to compare how informed Democrats are compared to Republicans, we could ask about things that progressives are more inclined to believe. For example...
How much student loan debt is held by the median 30 year old American? (The answer is zero)
Was the material on Hunter Biden's laptop fabricated? (Nope)
What percentage of homicides are committed with so-called assault rifles? (Roughly four percent which has implications for the effectiveness of an Assault rifle ban)
Does the median blue state resident pay more in taxes due to the removal of the SALT deduction? (Nope)
Are young African American men more likely to shot to death by police than to die in traffic accidents? (Nope)
Then we could compare the results to false things that conservatives are inclined to believe.
