Machine learning – just how predictable are we?

More importantly, what ethical considerations should be applied when using data and algorithms to target consumers?

Algorithms are already being used to help determine who’s approved for a loan, who is the best candidate for a job and which criminal is least likely to reoffend. But, how reliable are they… and what ethical considerations should be applied when using data and algorithms to target consumers?

Machine vs human – who is the winner?

In 2015, a study at MIT suggested that an algorithm could predict someone’s behaviour faster and more reliably than humans can. The Data Science Machine, created by a master’s student in computer science, was able to derive predictive models from raw data automatically – without human involvement. 

It’s fairly common for machines to analyse data, but humans are typically required to choose which data points are relevant for analysis. In three competitions with human teams, the machine made more accurate predictions than 615 of 906 human teams. And while humans worked on their predictive algorithms for months, the machine took two to 12 hours to produce each of its competition entries.

Fear not, this so-called fourth industrial revolution – where advances in computers, and artificial intelligence bioengineering are converging to change the way our world works – doesn’t spell the end for humans. It does, however, present an enormous opportunity for brands, marketers and communications professionals to more accurately understand consumers. Machines can be incredibly helpful, not to mention accurate, in analysing large amounts of data to inform decision-making with data.

Goodbye market research, hello Facebook

Historically, marketers and communicators have spent hours eavesdropping on research groups and pouring over market analysis in order to predict how humans will think and respond to a brand, product or service. With thanks to the emergence – and now domination – of social media networks, a whole new world of focus groups has materialised.

The way people talk on social media can be very different to how they talk in person. This means that the learnings from traditional focus groups often contrast greatly with what’s found from social media monitoring. Imagine, the power of combining these intelligent machines with a market research group of two billion-plus Facebook users.  Not only does this present the opportunity for to analyse consumer insights on scale, it also allows for insights to be measured in real-time. In an increasingly digital age where attention spans are short and audiences are fickle, the ability to be nimble with marketing and communications has never been more important.  

Listening to what works

Take for example, the work of make-up brand, Maybelline. When it launched its Hyper Sharp Liner in Hong Kong in July 2011, the product quickly became the brand’s No.1 liner. By 2013, the cosmetics market in Hong Kong had become increasingly competitive, with the emergence of new players with comparable products as well as competition from many other international cosmetics brands.

With the emergence of new players with comparable products as well as competition from many other international cosmetics brands, Maybelline decided to relaunch the Hyper Sharp Liner with a one-month integrated campaign that aimed to leverage off the increasing use of social media by the product’s target audience (15- to 25-year-old females).

By gauging the changes in the amount of buzz in social media about the Hyper Sharp Liner before and after the relaunch, Maybelline sought to understand how effective their strategy was. All the while, they mapped this against competitors’ buzz shares, measuring brand awareness and product perception for Maybelline and its competitors across major forums, blogs, social network Services, microblogs, and video and review sites.

This research was used to refine Maybelline’s strategy, and through the one-month communication campaign, Maybelline achieved a projected sell out of units. The a of the Hyper Sharp Liner, and also a significant increase against the average number of unit sold in 2012.
With the use of social media evolving at an increasing pace, this strategy verified social media channels significantly contributed to the transiting consumers from online to offline.

The ethical tightrope

The recent Facebook fallout highlights the scale of the moral dilemma today’s marketers must navigate – how much should we know about our consumers, and what role should ‘chief’ information, marketing and data officers play in ethical practices? While the field of big data is relatively new, the historic definition of ethical marketing should still apply: as a whole, brands should not engage in practices that result in negative or unsatisfying customer experiences.

This is something that is widely accepted and reinforced by peak bodies such as the Australian Marketing Institute. Whether a customer is left with a feeling of discomfort following a unsolicited telemarketing call, a door-to-door salesman or Facebook sharing data with a third party, the responsibility should fall with the company executives giving the directive – generally speaking, within the marketing and communications departments. The Facebook Cambridge Analytica scandal is an important reminder of our obligation to consumers, and that with the power that data affords, comes greater responsibility.

Data or bust

It is now hard to imagine a marketing and communications industry that doesn’t rely on data to inform strategy, new product development and campaigns. Much of what took place in marketing and communications, even as recently as a decade or so back, was based on assumption. We *think* that this product would be of interest to this audience, so we *figured* the best way to tell them about it would be mostly via a TV ad campaign.

But data is now essential for any smart and savvy marketer or communicator, and presents the opportunity to communicate with consumers with a level of insight that has never been more accurate or accessible.

While human behaviour is still not completely predictable, one thing that is for sure: the continued collection and analysis of data will certainly make us more predictable.

While affording brands enormous opportunity, this unprecedented access to consumer data must come with a movement of responsibility that will ensure the predictability of consumers is melded with ethical marketing practices.

Would you trust a brand more if an AI model recommended it? For many, the answer is yes – and it’s changing the very nature of PR & Comms.

Our latest report digs into the changing nature of trust, as audiences turn to AI models for quick answers instead of going to organisations or media outlets directly, with AI fast becoming the final stop in the comms cycle. 

This report unpacks:

  • Why trust has shifted, and where audiences are having these conversations
  • Why AI has become the last stop in the comms cycle
  • Methods for staying on top of your brand trust and reputation

If you ask ChatGPT or Gemini about your organisation today, the answer won't come straight from your website. Instead, it uses sources the model already trusts, which are often months or years old. So if your last big mention was a crisis or a controversy from 2023, that's probably still how AI describes you.

This is the tough reality for anyone working in PR and communications today. More people are getting their first—and sometimes only—impression of your organisation from an AI-generated summary, not from search results or the homepage. And these summaries often rely on outdated information.

What does freshness actually mean?

Content freshness refers to how recent the sources are that an AI model uses when it talks about you. It might seem like a minor technical point, but it's actually very important.

Search engines have always valued fresh content, and they let you update information quickly. If you change a page, Google recrawls it, and rankings can shift in days. Large language models don't work like this. As Lisa Main, Director at Main Bureau, said on Isentia's "AI as a Stakeholder" panel,  "large language models are not databases of verified facts." These models are trained on a snapshot of the internet, updated only from time to time, and they rely on sources that were already prominent when they were trained. This means a past crisis or a controversy that is already resolved can keep showing up in AI answers long after it's no longer relevant.

She shared the example of how a day and a half after a notorious terror attack, she asked ChatGPT if the area had ever experienced a tragedy of that type. It replied that it had not." The model wasn't being careless, but it just hadn't updated to include the latest news. This gap between what reality is and what AI still believes is true sums up the content freshness problem.

Dr Nici Sweaney, founder of AI Her Way, explained on the same panel why this gap matters. She calls AI "an accidental narrator" — it shapes what people believe about your organisation just by repeating the latest information it received. The system simply uses what's available and is not trying to be harmful, so it's important to make sure that information is up to date.

How does this change the way organisations show up?

For PR and communications teams, this changes what "reputation management" means. Put simply, messaging that an LLM cites will remain relevant, no matter when it dates from. Messaging that has not been factored into the LLM’s answers, meanwhile, will have no discernible impact on an increasingly vital - even central - channel, regardless of how many other metrics it might win out on. 

This leads to two important things to consider:

  • First, the conditions that surround recent earned media, statements, and announcements determine whether an AI model updates its picture of the brand, or keeps running on an outdated one. Catherine Arrow of the PR Knowledge Hub made a related point on the "Inside the AI Shift" webinar: LLMs and the agents built on them are "often forbidden from going behind paywalls, from scraping particular sites," which she said creates a kind of "news vacuum." The same logic applies to the brand’s own newsroom or press page. If it isn't feeding the model something current, the model has nothing current to draw from.
  • Second, owned content—like blog posts, media releases, and website pages — are strategically important because they’re something the organisation in question can control , but only if they are updated. If a page hasn't changed in eighteen months, it's much more likely to disappear from AI results, making any reputation built on it unstable. If something is published once and not updated, the brand risks letting older, less positive stories take its place.

For public sector and government communicators, the stakes are more immediate again. When a government agency's guidance changes, whether that's eligibility criteria, compliance requirements, or a service update, and the fresh version doesn't make it into what AI models are citing, people will still get fed old information, with potentially devastating real-world implications. 

The evidence is already there

This is not just in theory. It's playing out in global research and in the day-to-day data right now.

  • AI is quietly replacing the front door to your content

The Reuters Institute's Digital News Report Australia 2026 confirms that many PR teams have noticed that Google organic search traffic to news sites dropped by a third worldwide between November 2024 and November 2025, and by 38% in the US, as AI Overviews and AI Mode launched. Publishers expect this traffic to nearly halve again in the next three years. Some now call this trend a move towards "Google Zero." For communications teams, this means people are increasingly less likely to  click through to your website to check if information is current. More often, they're trusting what the AI says: hence why it’s so important to monitor content freshness.

  • AI models are now web-enabled and they might not actually guarantee source accuracy

One challenge is that most major chatbots are now web-enabled. For example, ChatGPT can browse the internet, Gemini uses Google Search, and Perplexity has its own live index. This makes it easy to assume that AI always knows the latest information. However, this does not mean that they are always accurate when it comes to citations. A study from Columbia's Tow Center for Digital Journalism tested eight AI search tools with 1,600 queries. They found that these tools failed to correctly identify or cite the source article more than 60% of the time. Some tools were wrong on most tests and rarely showed any uncertainty. New information has not had time to be checked or confirmed like older stories have. This is the real risk of relying on the newest updates — a story that is fast moving and poorly sourced about your organisation might end up in an AI answer before it’s even verified or fact-checked. 

  • People are turning to AI chatbots specifically for what's new

The same report found that 35% of people who use AI chatbots for news do so to get the latest media updates. Dr Sora Park from the University of Canberra's News and Media Research Centre explained on the "Digital News Report Australia 2026" webinar that the main reason people use AI chatbots for news is that "AI collates stories from different news sources into a single response." People expect these tools to provide current information. If your organisation's newest content isn't included (and you have something current or novel to communicate) you miss the chance to reach audiences when they're most interested.

  • Fresh content doesn’t always equate to ‘new’ content

A notable example  of creating freshness that LLMs reward and prioritise comes from updating existing pages, rather from creating brand-new content. Republishing and refreshing current material is more effective than many communications teams realise, as long as one actually updates the content, not just the date.

  • Evergreen pages are the first casualties when AI overviews roll in

The DNR Australia 2026 report also notes that once someone is inside an AI chatbot conversation, they rarely leave it to check the source — only 4% of AI chatbot users say they always or often click through to the original article, compared with 19% for search and 17% for social media. The pages that used to earn traffic just by sitting there, permanent and useful, are now the ones most likely to lose visibility, because AI models favour what's recent over what's merely correct.

  • One fresh statement doesn't automatically undo a stale narrative

If an executive online, especially one who has a lot of weight to what they post online, says something controversial and it quickly spreads across media articles, social media and search — it will definitely be picked up by AI as well. There is a golden window of opportunity that they need to capitalise on to clarify what they said. If they don’t, the negative story that was already built into the data AI models use, will not be affected much by the executive’s clarification statement, which wasn’t that timely anyway. As Catherine Arrow of the PR Knowledge Hub said on the "Inside the AI Shift" webinar: "public relations and media relations are not the same thing," and relying on a single release misses the point. The real lesson is not to publish faster after a crisis, but to build a strong, up-to-date presence before you need it. In our latest report, “How can leaders communicate in an age of scrutiny”, we’ve outlined exactly how comms leaders can communicate by adapting their content to audiences exposed to the “AI way” of news dissemination. 

What PR & Comms teams should actually do?

The challenge is that organisations can't make an AI model update its answers whenever they want. What they can do is track whether recent work is actually being noticed, which is what  Lumina AI View can help with.

Lumina AI View monitors which sources AI models use when talking about your organisation, how strong and recent those sources are, and how you compare to competitors. Freshness is one of five key factors in the overall score. If your freshness score drops, it's an early warning that your latest campaign or announcement hasn't reached the AI ecosystem yet, and older stories are still dominating.

What’s important to note is that the tool provides a list of source citations, paired with reputation pillars like direction, integrity, performance and innovation — giving a comms professional a fully-rounded understanding of what they need to do. It’s not just the case of knowing source citations, but also of understanding your own AI perception and performance to make informed decisions — whether that’s for a brand,a government agency, a NFP or elsewhere.

This kind of tracking is even more important because it shifts by industry and by market, so "AI visibility" doesn't mean the same monitoring job for every organisation. AI answers for healthcare might draw from the smallest, highest-trust pool of sources (mostly clinical and government), but SaaS and fintech answers lean heavily on editorial reviews and comparison sites.  Ngaire Crawford made a similar point regionally on the "AI as a Stakeholder" panel. For the APAC region specifically, she pushed back on the assumption that editorial media dominates AI citations — "there are a lot of really massive claims about the impact of editorial media... some as high as 85, 88%. That's not what we're seeing." Instead, she found "a fairly even split between (editorial media) and company content," alongside a real presence for review sites, forums, and academic sources. For a comms team, that means the freshness strategy that works for a media-heavy consumer brand might not work for a government agency whose AI visibility is really riding on review sites, .gov pages, or industry forums instead.

By tracking regularly — weekly or as a routine check— you turn the vague concern of "what is AI saying about us" into something that is super clear. You can see if recent coverage changed your list of citations, or if your owned content is still being found, or where there are gaps that need to be filled because old stories still exist and are causing problems.

The opportunity in staying current

There's a real advantage here too. If old content keeps you tied to an outdated story, fresh content is a direct way for PR and communications teams to influence how AI presents them. Publishing regularly, keeping your own pages updated, and getting recent, credible coverage is not just for human audiences. It's how PR professionals can make sure the systems shaping first impressions have the right information.

Teams that make it an ongoing habit of checking in regularly, watching for changes, and keeping fresh, credible content flowing, will have more control over how AI describes their organisation.
