The Science of 'Yes': How we get others to do what we want (and how they do the same to us) Resistance is futile...

My latest article breaks down the science behind how people get you to say "yes" and why learning this won't save you. I'd ask you to read it, but I'm going to start small and just ask you to click the link. (That's the foot-in-the-door technique. You're welcome.)

Abstract
Online media shapes public opinion, with messages from opposing information sources
deepening polarization. How content is framed and presented determines its meaning
and impact on readers. To date, studies on framing have focused on finding certain
phrases, topics, or ideas characterizing messages from particular sources, a strategy
providing only limited results. In this study, we used a broader, agnostic approach that
involves extracting the narrative from text, including its characters, plot, setting, and
moral of the story, and the relationships between these elements. We translated text
from tens of thousands of health documents in the language of conspiracy corpus
(LOCO) into representations called semantic graphs. We then compared these graphs
across documents from conspiracy and mainstream sources. We found that conspiracy
media framed health through belief, emphasizing immediacy and individual impact,
whereas mainstream media used scientific framing with a long-term, institutional focus.
Shared words carried divergent narratives. As one example, in documents related to
COVID-19, conspiracy media emphasized preventing violence rather than preventing
infection (the mainstream narrative). Understanding conspiracy narratives is crucial for
policymakers and media platforms seeking to curb their spread. This understanding can
inform efforts to boost media literacy and reduce the number of posts peddling
misinformation. We suggest using automated tools and AI as an aid in both efforts.

Figure 1. Translation of two sentences into semantic graphs with narrative elements
Note. We extracted the narrative elements of sentences from conspiracy and mainstream documents using an algorithm that translated the text into semantic graphs, as shown above, which omit grammar such as prepositions and verb tenses. Simplified semantic graphs for two sentences—one from conspiracy and the other from mainstream media—depict narrative elements by color: blue for plot, orange for character, green for setting, and purple for attributes of character or setting. The arrows connecting the rectangles indicate a direct semantic relationship between two elements.

Figure 3. Comparing narrative elements across conspiracy & mainstream media in three health-related subject areas
Note. Words representing predominant narrative elements—plot, characters and setting—in conspiracy and mainstream texts were mapped according to their semantic properties (typical use in a sentence). For instance, combat terms (war, destroy, military) appeared in the conspiracy graphics in locations analogous to those of disease terms (infect, disease, patient) in the mainstream maps. Similarly, an immediate timeframe (today, tomorrow) in conspiracy media appeared where specific weeks, months, or years showed up in mainstream texts.

Australia has a major climate disinformation problem – and fixing it will take a huge effort Senate inquiry wants more funding for climate research and digital literacy to address scare campaigns, and wants more studies on health impacts of wind turbines.

Embarrassing AI slip-ups and wind turbine syndrome made it into the final report.

Interestingly, it found the solution to climate and energy disinformation is to take a similar approach as Finland and Estonia are to Russian war propaganda 😭🔌

Abstract

Conspiracy theories are widely viewed as harmful to politics, and a growing number of studies have sought to identify their detrimental effects. Our study adds to this literature by examining whether brief, realistic exposure to conspiracy theories about a major political event can undermine individuals’ commitment to a broad set of democratic norms. We rely on two online survey experiments conducted in Brazil with a total of 8 thousand respondents. Participants assigned to the treatment conditions were exposed to conspiracy theories surrounding the stabbing of then–presidential candidate Jair Bolsonaro during a campaign event; control group participants viewed either the official account of the event or unrelated content. Subsequently, participants answered questions about democratic norms, institutional trust, and political hostility. We find some evidence that exposure to conspiracy theories reduces support for democracy, particularly in the electoral dimension. Surprisingly, non-partisans are more affected than partisans. Results also indicate that exposure to conspiracy theories reduces institutional trust but does not affect political hostility. However, the effects of conspiracy theories are not consistent across narratives, emerging more clearly in the one that blames the right for the event. These findings underscore the nuanced and specific nature of the influence of conspiracy theories on democratic values, which can help calibrate our concerns about these narratives.

Exposure to conspiracy theories decreases support for democracy and institutional trust, while having non-significant effects on partisan hostility. The estimates are derived from bivariate OLS regressions with conventional standard errors. Since the outcomes were collected in different studies, the sample size is n = 2, 401 for the model using the OSDI as the outcome variable and n = 3, 987 for the models with institutional trust and partisan hostility as outcomes

Effects of CTs across different dimensions of democratic support. Individuals exposed to con- spiracy theories are less willing to accept election results and less supportive of democracy in the abstract. Average treatment effect estimates with 95% (thin line) and 90% (thick line) confidence intervals for the causal effect of exposure to conspiracy theories on different dimensions of democratic support. The estimates are derived from bivariate OLS regressions with conventional standard errors. The sample size for all models is n = 2, 402

Exposure to Conspiracy Theories partially decreases trust in election results, make individuals slightly more willing to accept the Jan 8, 2022 attack to the Brazilian Congress, reduces beliefs that candidates should concede in the face of an electoral defeat, and decreases trust in elections. Average treatment effects with 90% and 95% confidence intervals (thick and thin lines, respectively). The models used to generate the figures are bivariate OLS regressions with conventional standard errors. The sample size is n = 3992 for all the models in the figure

The Famed 1967 Bigfoot Film Was an 'Incredible Hoax,' Says the Director of a Groundbreaking New Documentary Filmmaker Marq Evans stumbled upon film footage that had been locked away in a safe for decades that, he says, proves that the famous 1967 Patterson-Gimlin Bigfoot film was an "incredible hoax."

"What we eventually found out is that [this new footage] represented a trial run, a rehearsal that was never discarded.”
