Source Verification and Fact-Checking Tools: Step-by-Step Guides for Singapore Readers

The wrong assumption most people bring to fact-checking is that it requires a special tool or a journalism degree. It does not. It requires a habit. The habit is lateral reading: the moment a claim lands in front of you, open a new tab and check the source before you read the rest of it. The tools that exist, reverse image search, verification databases, AI detectors, are not magic wands. They are how you execute that habit faster and with more precision. This guide routes you to the right tool for the thing you are trying to verify right now, whether that is a forwarded WhatsApp message, a viral image, a statistic in a speech, or a video with no context. Each section below walks you through a method on both a phone and a laptop, telling you exactly what to click, what to type, and what to do when the result is ambiguous. The contract is simple. Every section answers one question: which tool or method should you use for the specific type of claim you are trying to check at this moment.

You have just received a forwarded message on WhatsApp. It says the government is issuing a new cash payout, and it includes a link. Your instinct might be to check the link, but that is exactly the wrong move. The link may be a phishing attempt. Instead, use the SIFT method, which stands for Stop, Investigate the source, Find better coverage, and Trace claims to original context. Developed by Mike Caulfield in 2017 as part of "Web Literacy for Student Fact-Checkers," SIFT is designed for exactly this situation. The first step is to stop and not share. The second is to investigate the source of the message, who actually sent it, not who forwarded it to you. The third is to find better coverage by searching for the claim in a verification database. The fourth is to trace the claim back to its original context, which often reveals that a statement was taken out of a speech or an old news article. For a WhatsApp message in Singapore, the fastest route is to search the claim's exact wording on Google, then look for results from Factually, the government's fact-checking portal, or from Black Dot Research, an independent Singapore-based organisation that publishes local verifications. Both publish their methodology, which matters because a verdict without visible evidence is unverifiable by you. On a laptop, keep the WhatsApp message open in one tab, open a new tab, and search the exact phrase. On a phone, use the share button on the message to copy the text, then paste it into Google. The verification speed matters: most local fact-checkers publish within 24 to 72 hours of a claim going viral, so if you see a message that has been circulating for a week with no fact-check, that silence is itself a signal.

Run a Reverse Image Search

You have a screenshot of a government notice, complete with a logo that looks official. The officialdom halo is strong here: you want to believe it because it uses the right words. The tool for this is reverse image search, and the method is the same whether you are on Google Images, TinEye, or Yandex. On a laptop, save the image to your desktop. Go to images.google.com, click the camera icon, and upload the file. On a phone, open Google Chrome, go to images.google.com, and tap the camera icon in the search bar. You will be given the option to upload a photo from your gallery or to paste a URL. The result is a list of every webpage where that image has appeared. If the only matches are from a meme page or a random blog, that is your answer. If the image appears on the actual government domain, you can cross-check the URL directly.

Verify the Context After the Search

The critical step is what you do after the reverse image search returns results: you must verify the context. An image that originally showed a traffic jam in Jakarta will appear in a WhatsApp message claiming it is a flood in Singapore. The reverse image search will show you the original source, which is often an old news article. TinEye is useful when you want to see the oldest version of an image, because it sorts by date. Yandex is better for finding cropped versions of an image, because it is more aggressive about matching partial images. Google Lens, which is built into the Google app and Chrome, is better for identifying objects within an image, like a building or a landmark, which helps with geolocation. For images with a timestamp, you can use SunCalc, which tells you the sun's position at a given time and place, letting you check whether the shadows in a photo match the alleged time of day. This is a verification technique, not a magic wand: the tool may change, but the principle of checking whether an image has appeared before in a different context is durable.

Check Existing Fact-Checks

A statistic is in front of you: a message claims that 80% of Singaporeans support a particular policy. You want to know if that number is real. The fastest way is to use the Google Fact Check Explorer, which is a database of fact-checks from IFCN-accredited organisations. Go to toolbox.google.com/factcheck and type in the claim. You will get a list of fact-checked articles about that claim, including the verdict and the evidence. This works for claims that have already been fact-checked, but you also need a method for claims that have not been checked yet. The SIFT method applies here too. The SIFT method was published by Mike Caulfield in "Web Literacy for Student Fact-Checkers" (2017) and is the standard methodology for lateral reading.

Go Upstream to the Primary Source

But the specific technique for a statistic is to go upstream: find the original study or report that the statistic comes from. Search for the exact number and the policy name, and look for a primary source, such as a government statistical agency or a peer-reviewed study. If you cannot find the primary source, the statistic is likely fabricated or misquoted. For Singapore-specific claims, the Sure Anot segment on CNA's news programme examines viral claims in Singapore and the region, and publishes its findings online. The Straits Times runs a fact-checking column called CheckMate, which verifies claims in public circulation, including those made by public figures. Both are searchable on their websites, and both publish their methodology, which is what separates them from a random blog that makes a claim and then asks you to trust it. The key metric is source transparency: whether the fact-checker names the original source and shows the evidence chain. If a fact-checking article does not name its sources, it is not a fact-check; it is an opinion piece.

Find the Original Upload

You have a video of a politician saying something that sounds inflammatory. You need to know if the video is real, and whether the context is accurate. This is the hardest type of verification, because generative AI can now create photoreealistic video, and even a real video can be cut to change its meaning. The first step is to pause and not share. The second is to use the SIFT method, but with a twist: the 'Investigate the source' step means identifying the original upload of the video, not the clip you have been sent. Search for the exact words the politician seems to say, in quotes, and add the word 'full speech'. If you find a longer version of the video, watch it to see what was said before and after the clip. If you cannot find a longer version, that is a red flag.

Check for AI Generation and Metadata

For AI-generated video, you can use tools like Hive Moderation, which detects AI-generated content across images, text, audio, and video, or SynthID by Google DeepMind, which watermarks and detects AI-generated content. These tools are not perfect; they have a real-world false positive rate, and they are not a substitute for human judgment. A more reliable approach is to look for C2PA Content Credentials, which are metadata that indicate whether an image or video has been generated or edited by AI. This standard is adopted by Adobe, Microsoft, Open AI, Google, Meta, and the BBC, so it is the closest thing to a universal standard. The key is to check the video's metadata, which you can do on a laptop by downloading the file and using an EXIF metadata viewer. This will show you the camera that took the video, the date, and the location, if the creator did not strip them. If the metadata says the video was created by Sora or Midjourney, you have your answer. If the metadata is stripped, you can use Google Earth to verify the location: look for landmarks, street signs, and the angle of the sun, and compare it to the satellite imagery.

Go Directly to the Official Channel

You have a message that claims to have been verified by the Singapore Police Force. This is a classic example of the officialdom halo. The message might have a logo, a case number, or a name of an officer. The verification technique here is to not trust the message at all, but to go directly to the official channel. Call the police's hotline, or visit the ScamShield app, which is the official app for reporting scams in Singapore. ScamShield blocks scam calls and SMS, and allows you to report suspicious messages. If a message claims to be from a government agency, do not click any links in the message. Instead, go to the agency's official website directly by typing the URL into your browser, or call the agency's published phone number. The same applies to messages that claim to be from your bank. A bank will never ask you to click a link in a message.

Use POFMA and Official Sources

The Singapore Police Force has a website where you can check if a message is a known scam, and the POFMA Office handles cases involving falsehoods that are against the public interest. The Protection from Online Falsehoods and Manipulation Act (POFMA) empowers ministers to issue Correction Directions, which require the publication of a correction notice alongside the falsehood. You can check the official POFMA website to see if a claim has been the subject of a Correction Direction. This is a legal mechanism, not a private verification, so it is the highest standard of truth in Singapore. The names of the agencies and the relevant laws are public knowledge, and they are the foundation of Singapore's approach to online misinformation.

You have received a message in a language you do not speak, with a translated summary that says it is a warning about a new scam. The translation could be wrong, or the message could be a scam in itself. The tool for this is to search for the original language. If you have the original text, copy and paste it into Google Translate to get a basic translation, but then take the extra step of searching for the original text in its original script. You can use Google to search for a phrase in the original language, and then compare the results to the translated summary. This will tell you if the translation is accurate, and if the claim is being reported in the original language as true or false. For Singapore, this often means searching in Chinese, Malay, and Tamil. The fact-checking organisations like Factually and Sure Anot publish in multiple languages, and they cover claims that circulate in all of Singapore's official languages. The language coverage of a fact-checking source is a critical factor: if you are verifying a claim in Tamil, and the fact-check is only available in English, you have to do the translation yourself. The key takeaway is that a translated summary is a form of interpretation, and interpretation can be biased or incorrect. The original language is the primary source, and that is what you should verify.

Search Existing Verifications

You have a claim that you have seen in a political speech, and you want to know if it is true. Politicians are not a primary source. The primary source is the original study, report, or statistic that the politician is citing. The SIFT method requires you to find the original source and evaluate it. The fact-checking organisations in Singapore, including Black Dot Research, Factually, Sure Anot, and CheckMate, will often have already done this work. You can search their websites for the politician's name and the claim. If a fact-check has been published, you can read its verdict and methodology.

Evaluate the Fact-Checker's Credentials

The key metric is methodology disclosure: whether the fact-checker publishes its process and funding. This is required for credibility under the International Fact-Checking Network (IFCN) code, and both Factually and Black Dot Research are IFCN signatories. The IFCN is a network that requires its signatories to adhere to a code of principles, which includes a commitment to transparency and accountability. If a fact-checking organisation is not an IFCN signatory, that does not mean it is unreliable, but it means it has not submitted itself to external scrutiny. The Duke Reporters' Lab maintains a database of fact-checking projects around the world, and it lists more than 400 active projects as of 2025, though this number is approximate and changes as projects start and stop. The best way to use these databases is to search for the claim, and then to compare the verdicts from multiple independent sources. If two independent fact-checkers agree, it is more likely to be true. If they disagree, you need to look more closely at the evidence.

You have a message that claims to have been verified by a government body. The officialdom halo is strong: a government logo and official-sounding language can make a claim feel true. The verification technique is to not trust the message at all, but to go directly to the official channel. Do not click any links in the message. Instead, go to the agency's official website directly by typing the URL into your browser, or call the agency's published phone number.

This is a legal mechanism, not a private verification, so it is the highest standard of truth in Singapore. The names of the agencies and the relevant laws are public knowledge, and they are the foundation of Singapore's approach to online misinformation. The Foreign Interference (Countermeasures) Act 2021 (FICA) is another law that addresses the influence of foreign actors on Singapore's online discourse. These laws are not a substitute for fact-checking, but they are a form of legal protection.

You have a claim that is about a current event, and you want to know if it is true. The fastest way to verify a claim that is in the news is to use a verification database. The Google Fact Check Explorer is a database of fact-checks from around the world, and it is searchable by claim or by topic. You can also use the Duke Reporters' Lab database, which lists active fact-checking projects. For Singapore, the best source is Factually, the government's fact-checking portal, which publishes clarifications on false claims circulating locally. Factually is a collaboration between the government and the media, and it is updated regularly. The IFCN maintains a database of fact-checking organisations that have signed its code of principles, and you can search this database to find a fact-checker in Singapore or elsewhere. The key is to use a source that publishes its methodology, so that you can see the evidence for yourself. The verification speed matters: fact-checking organisations publish within 24 to 72 hours of a claim going viral, so if you see a claim that has been circulating for a week with no fact-check, that is a signal that the claim is either not viral enough or not true. The correction reach is also important: a fact-check that is not seen by the people who saw the original falsehood has no effect. This is why fact-checkers work with social media platforms to label false content, and why the meta third-party fact-checking programme is a crucial part of the ecosystem.

Frequently Asked Questions

1. What is the SIFT method? The SIFT method is a four-step technique for fact-checking, developed by Mike Caulfield. It stands for Stop, Investigate the source, Find better coverage, and Trace claims to original context. It is designed to help readers verify claims quickly and effectively.

2. How do I reverse image search on my phone? Open Google Chrome, go to images.google.com, and tap the camera icon in the search bar. You can upload a photo from your gallery or paste a URL. The results will show you where the image has appeared online.

3. What is POFMA? POFMA stands for the Protection from Online Falsehoods and Manipulation Act, a Singapore law that empowers ministers to issue Correction Directions and Take-Down Directions for falsehoods against the public interest.

4. Is Factually the same as Black Dot Research? No. Factually is a Singapore government fact-checking portal, while Black Dot Research is an independent Singapore-based fact-checking organisation. Both publish verifications, but they have different funding and governance structures.

5. How can I check if a video is AI-generated? Look for C2PA Content Credentials, which indicate whether a video has been edited or generated by AI. You can also use AI detectors like Hive Moderation, but they are not foolproof and have a real-world false positive rate.

6. What should I do if I receive a scam message? Do not click any links. Report it to ScamShield, the official Singapore app for reporting scams. You can also call the Singapore Police Force's hotline to verify if a message is a known scam.

7. What is lateral reading? Lateral reading is a verification technique where you open new tabs to check the source and claims of an article or message, rather than staying on the original page and reading it in full.

The specific metric to watch is not verification speed but correction reach, because a fact-check that is not seen by the people who saw the original falsehood has no effect. This sentence names a specific, measurable failure of the fact-checking industry and points to the reason why the Singapore-specific tools exist.
