And of course this "moral stand" has nothing to do with subscriptions for Bell services...
or maybe the fact that Bell is actively trying to gain traction for their own brew of Netflix (CraveTV) is mere coincidence.
There has been evidence of this association floating around for ages. On the balance of evidence there may be reason for concern, but in particular as with anything in medicine, the right decision for any individual may come from presence of the right (or wrong) risk factors.
See e.g. : http://www.sciencedaily.com/releases/2012/11/121114083928.htm http://www.forbes.com/sites/alicegwalton/2012/01/11/the-neuroscience-of-pot-researchers-explain-why-marijuana-may-bring-serenity-or-psychosis/
One factor that would seem to be relevant is the proportion of THC and cannabidiol (http://en.wikipedia.org/wiki/Cannabidiol) present in plant strains, and change in ratios from decades past as plant breeding has changed the landscape of what effects may be expected from a particular plant.
The extreme reaction of "Reefer Madness" is almost certainly misguided, but there is reason to suggest that more science is needed towards ascertaining that the full benefits may be had, and risk factors removed (e.g. via genetic tests and controlled breeding/testing of plant strains) whether for medicinal purposes or otherwise.
With respect to i., I'm hoping there's a biologist out there that is able to shed some light on a general question in this area of study:
Does the conclusion of this work amount to more than "one branch of a classification tree derived from observed data is more intermixed with another branch of the tree than previous data showed"?
I'm not trying to say anything about differences in people, or comment on methods in this area of study - but rather to understand the broader context of the reported results. Is the critical consideration that evolution tends to follow a continuum, but there are critical junctures where a mutation or two significantly changed the population dynamics subject to time, competition and environmental conditions? Is it a matter of coarse-grained as opposed to fine-grained changes over time, and where does one draw the line for coarse?
When you connect your social media account to somethiing, it's reasonable to expect that every permission that they describe they are requesting they are actually going to use. If you're not comfortable with this, then don't connect the account to the service. Period.
"Stupid users" is a bit harsh. I'm sure that there is a reasonably large group of individuals that are relatively intelligent, but don't understand the technology and what they're signing up for. "To(o) lazy to read" is also pushing it. Terms of service, EULA's etc. are typically exceedingly long, and also sometimes verge closer to legalese than what many are used to reading. Prior to the inception of "big data", and privacy concerns coming front and center, I'm sure that many people were in the habit of simply clicking "agree" since it didn't matter all that much. Today this is much less true. The notion that "stupid people" should know better than to "agree" to something without knowing what they are agreeing to is potentially a dangerous doctrine to be pushing. Consider a con artist, or e-mail scam, or any scenario where there is someone gaining at the expense of someone else. Perhaps some blame lies with the victim, but certainly there are many scenarios where the finger can be pointed squarely at the aggressor.
I have yet to see any problem, however complicated, which, when you looked at it in the right way, did not become still more complicated. -- Poul Anderson
