Or, to the jaded: “They observe the world with blinkers; they rely on theories their own camp has already debunked… by editing that out; they collect data to suit their theories and reject those that don’t conform to them; they are too often captured by ideological preferences and preconceived notions - and paycheques or tenure paths; and they are rarely open to changing their minds when presented with better theories or new data, especially from heterodox schools or other disciplines.”

New quantum computer smashes 'quantum supremacy' record by a factor of 100 — and it consumes 30,000 times less power.
Nice to see real progress is still happening, even if most of the economics sphere remains stuck in the Dark Ages. livescience.com/technology/com…

More people means more cars and the need for more highways.
So when will the Green Party start calling for lower immigration to reduce demand for roads and highways?
Reducing population growth was one of the key parts of the environmental movement, yet the GPO is afraid to raise the issue of high immigration.

bro just one more highway bro, bro I swear just one more highway and it'll fix the traffic bro.

NEW - “The 413 is critical” says Premier Ford when asked about reports that the proposed new east, west highway won’t noticeably lower congestion on other routes “The more highways, the better it is” says Ford.

#Canada is trying to bump up its population growth through #immigration amid dwindling birth rates, but a better #economy doesn’t equate to a larger one and this approach could prove to be no more than an economic stopgap.

It was a pleasure speaking with @QuantumDaily about quantum models in economics

The #volatility smile can seem illogical from the perspective of classical #finance, but applying quantum logic allows us to see that it accurately describes a genuine aspect of the #market.

"...some in academia are starting to take quantum ideas a little more seriously but an interesting question is why it took so long."

"Its trick is to present itself, not so much as a prediction, but rather as a magical machine which somehow defines the correct option price – like a mentalist who predicts the future by making it happen."

@Doctoroid1 @CQFInstitute The talk can be seen here (free registration required): cqfinstitute.org/video-series/b…
I am working on an update to the 3rd edition, should be ready by end of the year

@d_orrell @CQFInstitute Very interesting! Was the talk recorded and, if so, is it publicly accessible? On another note, is your 3rd edition of "Quantum Economics and Finance" substantially different from the 2nd (which I bought just b4 the 3rd came out)? Is a 4th edition planned soon? Many thanks

It was a pleasure speaking yesterday at the @CQFInstitute conference marking the 50th anniversary of the Black-Scholes model. My talk presented 9 predictions of the quantum model.

A stunning, entertaining critique of psychology. Many points apply to anthropology, political science, and sociology. #EconTwitter : many also to economics? experimental-history.com/p/im-so-sorry-…

Open call for high-impact topics in quantum social science! The @OhioState Quantum Soc. Sci. Bootcamp is creating Top 5 lists of potentially high-impact articles that could be written in various disciplines. Share your ideas below: rb.gy/2c2gs

@d_orrell Thanks for this post, I appreciate you posting this information onto twitter. I've been interested your work, and was wondering whether you would be open to doing podcasts?

The Nobel prize-winning model has been heralded as a game changer for #traders but in making sweeping assumptions about #growth and #volatility, it is perhaps not quite as elegant as it seems.

Today is the day, pop in to listen to @EmmanuelPothos, from our Editorial board discuss quantum cognition, all are welcome! u.osu.edu/quantumbootcam…

Models aren’t just tools to analyze systems, they also affect what we do and don’t see. And in finance, the quantum model isn’t too much of a stretch – it’s a perfect fit. Which is why we started a new journal: us.sagepub.com/en-us/nam/quan…
