does not have effect

Originally proposed at Wikidata:Property proposal/Generic

   Done: does not have effect (P7167) (Talk and documentation)

Description	usual effect of the general cause absent here
Data type	Item
Example 1	heat lightning (Q1993841) → thunder (Q83301)
See also	has effect (P1542) has characteristic (P1552) and does not have characteristic (P6477) has part(s) of the class (P2670) and does not have part (P3113)

Motivation

lightning^(Q33741) has a nice statement with has effect^(P1542)=thunder^(Q83301).

heat lightning^(Q1993841) should probably have one that notes its absence. I used does not have characteristic^(P6477), but that seems suboptimal as that property completes has characteristic^(P1552).

I suppose we should find more samples before moving ahead with this. Please contribute. (Add your motivation for this property here.) --- Jura 16:35, 5 August 2019 (UTC)

SELECT ?item ?itemLabel ?value ?valueLabel ?subclass ?subclassLabel 
{
	?item wdt:P1542 ?value .
	?subclass wdt:P279 ?item . 
	MINUS { ?subclass wdt:P31 wd:Q3231690 }
	SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}
LIMIT 1000

Try it!

Some of the subclasses of items with has effect (P1542) might be good candidates for this properties, i.e. cases where the subclass doesn't have the effect whereas the class does. --- Jura 09:53, 7 August 2019 (UTC)
