Subjective cognitive decline is a 'subjective' because it is perceived by the individual themselves. This means one of: 1) Weed dramatically reduces cognitive impairment. 2) Weed dramatically reduces an individual's ability to accurately asses their cognitive ability. 3) People who use weed are, for some other reason, dramatically less likely to suffer from cognitive impairment, or dramatically less able to accuratel…

Marijuana tends to affect people in one of two ways: they either get subdued or they get infatuated. Many people appear to get calmed and relaxed, they could just go to sleep, with pot affects them. Those that marijuana infatuate tend towards creative, intellectual, and creative intellectual pursuits. I am one such infatuated pot smoker, which I keep pretty much secret, because due to my pot smoking infatuations I've gradually made my way into uber secure work environments simply because I'm competent and fascinated by the work; while my counterparts are constantly burning out. It's a job to them. To me, it's fascinating play.

Earlier quoted context omitted.

From my personal experience, having several friends that have been smoking since high school up to now (mid 30s), it's definitely 2).

But maybe having friends who smoke weed dramatically reduces your ability to assess your friends' assessment of their own cognitive ability.

Indeed, touché

Is there a journal or news site that exclusively publishes on studies that have been replicated?

There should be a whole library of such studies, perhaps even with more than one successful replication. All signal, no noise. Entire disciplines would be absent from it

Imagine if academic success were measured by having studies in such a library. Not just the original, but also the replications! Somehow we'd also need to incentivize publications of non-successful replications just as much though.

Just to be clear, 96% decreased odds of cognitive decline = good? Rather confusing way to put it

No, of subjective cognitive decline. Not decline as measured through testing, decline as self-reported. Basically pot makes you less self-aware.

My personal experience and in some cases a negative one. Cannabis makes me hyper self aware to the point of over analyzing myself.

What is SCD?

Subjective Cognitive Decline (SCD) refers to an individual's self-perceived experience of worsening or more frequent confusion and memory loss, not necessarily confirmed by clinical diagnostics.

Another explanation is that weed smokers are less likely to self-report cognitive impairment, as that suggests it’s self-inflicted, which would cause feelings of regret and shame in many I suppose.

Yes, cognitive dissonance. This is my hunch.

The study is really broken from the beginning:

ask someone who take drugs to assess their own capacities, instead of measuring those from an objective perspective.

Obviously, "yes cannabis affects your ability to self-report your cognitive abilities";

it's a psychoactive drug that is mainly used for its cognitive effects, it's the main use/"advantage" of it ! (more rarely for pain management)

It's like if you ask alkaloidal cocaine (crack) users how they feel about their abilities.

They may report amazing bodily control enhancement, and seen from the outside it may be very different.

Even alcohol users, at the exit of night clubs, you sometimes see them report self-report increased abilities and decide to drive.

In that case, asking them to self-report doesn't give you much info on their actual abilities.
