Here is an example of a problematic inference:
1. Mary has cybersex with many different partners
2. Cybersex is a kind of sex
3. Therefore, Mary has many sex partners
4. Having many sex partners - high chance of getting STDs
5. Therefore, Mary has a high chance of STDs

The eternal flaw in all this, it seems to me, is that you are still doing
logic which assumes that agents know what the premises refer to, and those
premises can be taken for granted.
Real world thinking, which is vastly more important and extensive than the
logical variety, is interested in
I didn't emphasize the first flaw in logic, (which is more relevant to your
question, and why such questions will keep recurring and can never be
*methodologically* sorted out) - the assumption that we know what the terms
*refer to*. Example:

But your examples are still symbolic in nature. I don't see why they
can't be reasoned via logic.
In the above example the concept sex may be a fuzzy concept.

It is an application of the rule error. One of my main arguments is
that while weighted reasoning systems (such as fuzzy logic) could be
shaped to accommodate this kind of rule error (by finding the
additional information that is needed to resolve it), I believe it is
more insightful to recognize
Exclusively searching KB for all possible derivations on a given
statement will lead to combinatorial explosion. What NARS does is to
resolve conflicts whenever they are encountered by the system. That
is, the system looks for better (more confident) conclusions until
spent all the time allocated

We only know that:
P(sex | cybersex) = high
P(STD | sex) = high
If we're also given that
