Causal

Indeed, some writers do not think the relation of brain to consciousness is a causal relation in the first place.

What is the difference between a causal relationship and a casual relationship?

Good conductors of heat are usually good conductors of electricity, but that puts the causal relation backwards. Conduction-band electrons can't help but transport kinetic energy, which--randomized--is heat. Putting heat before electricity is reasonable only because of the rarity of materials like diamond that conduct heat via the quasi-particles called phonons, which are communicable crystal-lattice vibrations.

There's no causal connection.

Is there a causal relationship?

It is unknown whether smoking causes depression or whether the causal direction goes the other way.

The World Health Organization reports evidence is accumulating of a causal link between the Zika virus and two neurological disorders — microcephaly, which causes brain abnormalities in newborn babies — and Guillain-Barre Syndrome, which can result in paralysis.

Despite its varying legality, cannabis is not usually labeled as a causal factor in terms of death.

There is no causal relationship between eating carrots and seeing in the dark.

No matter how often B follows A, and no matter how initially obvious the causality of the connection seems, the hypothesis that A causes B can be overturned by an over-arching theory which shows the two as distinct effects of a common underlying causal process.
